Re: 100k miles on 2006 convertible, a bad idea?
That type of driving sounds like mostly highway, which these cars thrive on. There's a forum member with an SRT6 with 175k and another with a n/a with 214k, and no major problems. The price should just reflect the high mileage. I would also ask for service records and get it inspected. I was putting 20-30k a winter on my Audi A6 and at 184k miles it is in excellent shape...but the key was doing the maintenance and not abusing it.
