7000 miles is not high mileage on these cars, at all, mechanically. This MAY have applied to Italian exotics of old, but now, they are engineered extremely well, as a whole.

Would you be wary of a one-year-old Toyota Camry with 7000 miles?

Sorry, this is a bit of a pet peeve of mine, this notion that exotic cars will implode if driven for more than a few miles a year, if any! Think of it this way - the car that has been driven, will have its problems revealed and already sorted out.

Good luck in your search - and don't limit yourself simply due to mileage!
