2018 Lexus IS 250 — should you buy one?

Why people love the 2018 Lexus IS 250

The 2018 IS 250 uses a 2.5-liter V6 paired with an 8-speed automatic that feels less dated than the 6-speed in earlier models, and owners praise the buttery smooth shifts when you're cruising on the highway. The F Sport trim adds a limited-slip diff and sportier tuning that makes the car feel planted through corners without sacrificing that Lexus-grade quiet interior. People keep these cars past 150k miles because the engine rarely needs more than oil changes and spark plugs.

Common complaints and known issues

The 2018 model year started getting reports of infotainment touchpad lag and occasional freezes around 40k–60k miles; Lexus pushed a software update but not all owners found it. Transmission hesitation under light acceleration showed up in some examples by 80k miles, though it's inconsistent and sometimes clears after a dealer reflash. Sunroof drains clog more often than they should, leading to interior water pooling by 100k miles if neglected.

Typical asking price

Under 80k miles: $18,500–$22,000. 80k–140k miles: $15,000–$18,500. Over 140k miles: $11,000–$14,500. F Sport trims command $2,000–$3,500 premiums. Accident history and regional auction sales (flood-prone markets) can drop prices 15–20 percent from the baseline.

Ranges are typical 2026 asking prices, not appraisals. The actual fair offer depends on this specific car's title history, accident record, and open recalls — which is what EstimateProof tells you.
