The Lexus IS 300h (XE30) is the executive saloon the German default crowd forgets to shortlist, and that oversight is exactly where the value sits. This is the third-generation IS sold in the UK from 2013, a rear-wheel-drive self-charging hybrid that pairs a 2.5-litre petrol engine with an electric motor for around 220bhp. Owners rate it among the most dependable cars on British roads, running costs are modest, and clean facelift examples now trade well below an equivalent BMW 3 Series or Audi A4. Our view: buy the right year and trim and you get a near worry-free premium saloon for the money you would otherwise spend fretting over a German rival’s repair bills.
What real owners say (CDE data)
CDE reviewed owner discussion across the Lexus Owners Club IS forum and PistonHeads alongside the published Auto Express Driver Power satisfaction data and the gov.uk DVSA recall record (checked June 2026). We have not driven or inspected every individual car referenced; this is aggregated owner signal, not a hands-on test.
- Most praised: refinement and cabin quietness, build quality, and genuinely low-stress ownership; the IS topped an Auto Express Driver Power owner satisfaction survey ahead of the BMW 3 Series.
- Most criticised: the e-CVT drone under hard acceleration, a firm ride on the larger F Sport wheels, and the fiddly pre-facelift Remote Touch mouse controller.
- Reliability signal: Lexus repeatedly finishes top or near-top of UK dependability surveys, and the DVSA holds only a small number of recalls for this generation, so check each car’s registration on the DVSA recall lookup rather than assuming it is clear.
Why the XE30 is the overlooked premium bargain
The third-generation IS launched in the UK in 2013 and stayed on sale through the rest of the decade, with a styling and equipment update for the 2017 model year and a heavier facelift following in 2021. Almost every UK car you will find wears the 300h hybrid badge: a turbocharged IS 200t and an early V6 IS 250 were offered, but the hybrid was the overwhelming volume seller and is the version this guide concentrates on. It competed directly with the BMW 3 Series, Audi A4 and Mercedes C-Class, yet it never matched their sales, which is precisely why it now looks like such good used value. If you are coming from an SUV and want to understand the wider Lexus hybrid range, our Lexus NX used buyer’s guide covers the same low-stress ownership case in a family crossover.
The hybrid powertrain: how the 300h actually drives
The hybrid pairs a 2.5-litre four-cylinder petrol engine with an electric motor for a combined output of 223PS (around 220bhp), driving the rear wheels through an e-CVT automatic. Carwow’s road test recorded 0-62mph in roughly 8.3 seconds, only a few tenths behind a contemporary BMW 320d, and the car will creep along on electric power alone for short stretches in town. The trade-off, as Auto Express and Top Gear both note, is the e-CVT drone: ask for a hard overtake and the revs flare ahead of the road speed. Drive it the way it wants to be driven, smoothly and unhurried, and it is one of the quietest, most relaxing executive saloons at the price. For the larger limousine take on the same hybrid philosophy, see our Lexus LS 500h used guide.
Which year and trim of Lexus IS 300h to buy
Our pick is a post-2017 facelift car in Luxury or Premier trim. The 2017 update brought full LED headlamps, a wider media screen on higher trims, and switched the awkward mouse controller for a trackpad, so the cabin feels far less dated to live with day to day. Avoid an early high-mileage F Sport on 18-inch wheels if ride comfort matters to you, because the firmer suspension and lower-profile tyres are the most common owner gripe. Luxury and Premier trims add heated leather, a powered boot and the better infotainment, and they barely cost more used. The pattern of paying for the cleaner, better-specified car rather than the cheapest example is the same one we set out in the Lexus ES used buyer’s guide, the front-wheel-drive saloon that followed the IS in spirit.
Known faults and the checks before you pay a deposit
The XE30 is genuinely tough, but a used hybrid still needs sensible checks. The hybrid battery is durable and rarely a problem, yet you should ask for evidence the system has been health-checked at a Lexus service; cars with full Lexus history can qualify for the Lexus Hybrid Health Check warranty extension. Because regenerative braking does most of the slowing, brake pads last a long time, so on low-mileage cars inspect the discs for corrosion and lipping rather than assuming light wear means new brakes. Confirm the small 12V auxiliary battery is healthy (a flat 12V is the most common no-start), check the infotainment responds and the parking sensors work, and run an HPI-style finance and write-off check plus the gov.uk MOT history. The same discipline of buying on boring, complete paperwork runs through our Lexus GS used buyer’s guide, the larger executive saloon from the same era.
Used prices and what your money buys in 2026
Used IS 300h pricing in the UK runs from roughly £8,000 for an early, higher-mileage 2013 to 2015 car up to around £20,000 for a low-mileage post-facelift Premier (Auto Trader and AutoUncle UK listing analysis, June 2026). The sweet spot for our money is a 2017 to 2019 Luxury with full Lexus history and under 60,000 miles, which tends to sit in the £13,000 to £16,000 band. Set that against a comparable BMW 3 Series or Audi A4 of the same age and you are usually paying similar money, but with a far lower risk of an expensive turbo, DPF or dual-clutch bill down the line. That stress-versus-price logic is the same reason we rate the Lexus RX 450h used buying guide so highly for SUV buyers.
| Spec (IS 300h) | Figure | Source |
|---|---|---|
| Engine | 2.5-litre petrol plus electric motor (self-charging hybrid) | Parkers |
| Combined power | 223PS (around 220bhp) | Carwow |
| Drivetrain | Rear-wheel drive, e-CVT automatic | Parkers |
| 0-62mph | Approx 8.3 seconds | Carwow road test |
| Combined economy | Roughly 48 to 67mpg by trim and wheel size | Parkers |
| Used price band (2026) | About £8,000 to £20,000 | Auto Trader |
Running costs: tax, insurance and servicing
Running costs are where the IS quietly wins. CO2 emissions from around 97g/km on the smaller wheels mean modest road tax for cars first registered before April 2017, and the hybrid drivetrain regularly returns 45 to 55mpg in real UK driving. Servicing at a Lexus dealer is reasonable for a premium badge, and the long brake life and clutch-free transmission keep consumables down. Insurance groups sit in the mid-20s to low-30s depending on trim, lighter than many German rivals of similar performance. The clincher for long-term buyers is the Lexus Relax warranty: a car serviced at a Lexus dealer can carry up to 10 years or 100,000 miles of cover, renewed at each main-dealer service, which is unmatched among the German alternatives. It is the kind of low-cost, low-drama ownership case we keep coming back to across our used premium buying guides.
How it stacks up against the German trio
On badge snobbery the BMW 3 Series and Audi A4 win, and on driver engagement the rear-drive BMW is sharper. But on the things that empty a used buyer’s wallet, the Lexus is the calmer choice. There is no diesel particulate filter to clog on short journeys, no twin-clutch gearbox to rebuild, and the hybrid system has a decade-plus track record of holding together. The owner-satisfaction gap is stark: Lexus owners voted the IS the best car to own in a Driver Power survey, with the 3 Series languishing far down the same table. If you value a quiet life over a 0-60 bragging right, this is the rational pick, and the cross-shop logic mirrors what we found in the Lexus UX used buyer’s guide.
Where to check a Lexus IS before you commit
Before any deposit changes hands, work through these UK checks:
- Run the registration through the gov.uk MOT history service for advisories and mileage consistency.
- Check the plate on the DVSA vehicle recall lookup and confirm any outstanding work is done.
- Browse current stock and price benchmarks on Auto Trader and read the owner experience on the Lexus Owners Club forum.
- Ask for full Lexus or specialist service history and evidence of a hybrid health check, which keeps the Lexus Relax warranty live.
- Run an HPI-style finance and write-off check, and verify the V5C details match the car.
- Browse Lexus Approved Used stock for the comfort of a manufacturer-backed warranty if your budget allows.
Our take
Our score: 8.5/10
The Lexus IS 300h is the thinking buyer’s used executive saloon. It will not thrill you on a back road the way a BMW 3 Series can, and the e-CVT drone under load is a genuine character flaw you should test-drive before committing. But weigh that against a near-spotless reliability record, the lowest stress in the class, real-world economy in the high 40s, and a main-dealer warranty that can stretch to 10 years, and the case is compelling. We would buy a 2017 to 2019 Luxury with full Lexus history in the £13,000 to £16,000 band, walk away from a cheap, patchy-history F Sport on big wheels, and treat a missing hybrid health check as the one risk that flips the decision. For a UK buyer who wants premium ownership without the German repair lottery, this is one of the smartest used saloons you can buy.
Is the Lexus IS 300h reliable?
Yes. Lexus consistently finishes at or near the top of UK dependability and owner-satisfaction surveys, and the IS itself topped an Auto Express Driver Power survey ahead of the BMW 3 Series. The hybrid system has a long track record, with the main weak points being the cheap 12V auxiliary battery and brake-disc corrosion on low-mileage cars rather than anything expensive.
How much does a used Lexus IS 300h cost in the UK?
Expect roughly £8,000 for an early high-mileage 2013 to 2015 car and up to around £20,000 for a low-mileage post-2017 facelift Premier, based on Auto Trader and AutoUncle UK listings in June 2026. The value sweet spot is a 2017 to 2019 Luxury with full Lexus history and under 60,000 miles, typically £13,000 to £16,000.
Is the Lexus IS 300h a plug-in hybrid?
No. It is a self-charging hybrid, so you never plug it in. A 2.5-litre petrol engine and an electric motor work together for around 220bhp, and the battery recharges through regenerative braking and the engine. It will run on electric power alone only for short, low-speed stretches in town.
What is the best year of Lexus IS 300h to buy?
A post-2017 facelift car. The 2017 update brought full LED headlamps, a larger media screen on higher trims and replaced the awkward mouse controller with a trackpad, so the cabin ages far better. Luxury and Premier trims are our pick over an early F Sport, which rides firmly on its larger wheels.
Does the Lexus IS 300h have rear-wheel drive?
Yes. The XE30 IS 300h is rear-wheel drive, which is unusual for a hybrid saloon and helps it feel more balanced than the front-drive crossovers many buyers cross-shop. Drive goes through an e-CVT automatic rather than a conventional gearbox.
How long is the warranty on a used Lexus IS 300h?
Through the Lexus Relax programme, a car serviced at a Lexus dealer can carry up to 10 years or 100,000 miles of cover, renewed at each qualifying main-dealer service. That makes service history the single most valuable thing to check, because it keeps the warranty alive and protects the hybrid components.
