Tough call.... options vs. low miles. I'd probably opt for low miles. I've always thought the carbon fiber add ons were fluff. I'd think if you bought the low mile car you could drive 10K guilt free miles, and with the possibility you could sell it in a year for what you bought it for??? As stated above, the low mile car is a low optioned car and likely has iron brakes. I think the iron brakes are perfectly adequate, but I bought a car with the CCB's mostly for resale value - time will tell. I also agree with whoever said that resale value drops on high mileage supercars...... I toil every time I drive the car thinking I'm devaluing it by driving it, but what's the point of owning if you don't drive it and enjoy it? Anyway, I vote for low miles.......
And BTW, with the rebate and big dealer discount I bought a mid level car ($184,100 MSRP). The cheap cars weren't getting the larger dealer discounts, and for just a few thousand $$ more you could get $20k in options...... It was difficult to find exactly the perfect car, so when I found one that had just about the right level of options, I pulled the trigger. I was not a big fan of the cars fully loaded with CF, but ended up with a carbon fiber roof and engine cover, both of which have really grown on me as I've owned the car.
I really wanted the rear carbon fiber spoiler, but it wasn't meant to be and the "spoiler-less deck has grown on me too!!
