Lexus SC430 (2001 – 2009) Review

Lexus SC430 (2001 – 2009) At A Glance


+Effortlessly swift, luxurious and refined alternative to the Mercedes SL, complete with folding hard-top and first-class build quality.

-Rides poorly on runflat tyres. Rear seats are tiny. Curious front-end styling.

On average it achieves 105% of the official MPG figure

Solar battery chargers
"We have two cars parked in a secure driveway (Ford Kuga and Lexus SC430) and are planning on being out of the country for the whole of December and into early January. Would it be wise keep the batteries trickle charged while away? Rather than removing the batteries from the cars my garage suggests using a couple of solar powered chargers which seem to abound at various prices but I'm just wondering if they are likely to be any good in winter? Added to which, I'm planning on keeping the Lexus under its cover which will exclude sunlight."
Whether they will work depends partly on whether the car batteries are hardwired to their accessories sockets, because if the battery won't charge through the accessory socket you need to connect the chargers directly, or build in charging points. And partly how much sun we get over December and January because if the car is covered in snow (or a cover), no sunlight will get to the charger. There is also a slight risk of fire. Depending on what codes you lose by disconnecting the batteries it might be better to remove them and keep them in a warmer place than the cars. If the batteries are healthy, if there are no draindowns in the cars and if you take both cars for a 40 mile run before leaving them standing there is a chance that will put enough in the batteries to last for 5-6 weeks without being disconnected.

Which is better: Lexus IS250C or recent Lexus SC430? I like them both!
"I am looking for a second car that will do 5000 miles a year. Has to be a CC (metal roofed convertible). The SC430 has a magnificent interior and great touring performance, but is a bit ugly and is greedy. The IS250C is modern, more funtional but is slower and a bit bland inside. I have read your review of the IS (many thanks) and looked in great detail at both cars but, hell, I like them both!"
Definitely go for the IS250C. Used now from about £22,500.
