It was cheap! Pics to follow when it's not filthy... It's had a knock on the NSF corner a few years ago which wasn't repaired all that well - I'll stick a new wing on it, probably a bumper cover too. The appeal of this one was that it's newer and lower milage than I'd otherwise budgeted for, it was cheap enough to still be quids-in once it's all sorted, and also the minor point about it still being under extended warranty, which I can extend for another 2 years...
I was never really interested in the non-hybrid GS. Would have preferred an LS to a GS430, and the 300 didn't really excite me... I was originally looking for an LS430, but my local Lexus specialist convinced me that the 450h was the way to go. Once I'd driven one, it wasn't going to go any other way!
