I'd definitely autox an LS430 now that I know you can get max poerformance summer tires and coilovers for it.
Once I can afford another car I'm definitely doing this! Even if my next car probably won't be an LS430, but my next car will be a hoot. My current car does need a bit of work to be trackworthy and by the time I'd be able to do it I'll just get another car.
I do like the Matrix/Vibe 2ZZ, but they're not quite "crossoverish" enough to "look like they don't belong" on an autox.
So, does anyone on oppo autox something that "doesn't belong" there? And yeah, I know that there's no such thing as a car that doesn't belong on the track, but you know what I mean! I know someone here has that bench seat Impala. Anyone else though?
