Before you buy
Inspection Checklist
What to verify on any candidate car.
Engine
1UZ-FE should be silky at idle; verify timing-belt service on 90k+ examples.
Suspension
Air-suspension compressor and bag condition if equipped; coil-converted cars are often the pragmatic choice.
Rust
Rear subframe and rocker panels on Northeast cars — deal-breaker if severe.
Starter
Slow cranks are a warning — labor-heavy repair.
Interior
Wood trim and leather condition indicate real ownership care.
