Pre-purchase report
180,000 miles · 4.0L 1UZ-FE V8
6 known failure points for this generation · cost data pending verification
A supremely durable luxury sedan that runs forever if maintained, but it is old now and the money goes into rubber, seals, and suspension bushings rather than the drivetrain. The 1UZ engine is nearly bulletproof; everything around it ages.
AI-drafted profile
