Used Lexus SC430 Open 2001 - 2009 reliability

There's plenty to go wrong on one of these cars because the equipment levels are so high. But Lexus has a reputation for building bulletproof cars, so you'll be very unlucky to find anything going wrong. All the same, make sure that any electrical problems are ironed out before you buy, and check the service records, particularly on older models, which might be a bit more vulnerable in this area.

It's also worth looking out for the more attractive revised later models. You can spot these from modifications that included changes to the grille, front fog lamps and bumpers, a six-speed 'box and adaptive front lighting. The rear lights were changed to LEDs and the revised alloy wheels on the later models make the whole car look smarter.

Finally, watch out for slow roof mechanisms: the roof should fold back within 25sec, so get your stopwatch out.
