I'm the guy with the 50 mile ITR. I agree, the car should be driven if you're going to buy it. I bought it concurrently with my former fiance, so although the car was primarily in my name to finance it, it was really her car. She agreed at that time to make all payments - that didn't happen. She got several thousand dollars behind, and we've long since broken up - so I had to go and get the car so I can sell it.
The car was literally driven from the dealership to her house and that was it. It went around the block twice in 3 years. The next time it was driven was last weekend - from her house to my shop. I need to drive it to my insurance company to get it fully covered, so it will get a few more miles on it then - but I have no idea why she got it and didn't drive it. We got a yellow one also which I also had to go get - she did drive that one so it has 36k miles on it - but the black one just sat.
If you just drive an ITR on weekends, special occassions, etc. and drive a beater daily that makes sense to me - but not just keeping a car as a collector's item or something. Just my .02.

 

'00, 2500 miles. I only take it out to beat it at the track or auto-x.
WRX is my daily driver and winter skimobile.

 

I bought my ITR 2 months ago from Philly. Got it with 27.1k miles. Just passed 28.5k. I don't drive it because I work 90+ hour work weeks not because i'm babying it. That car don't know what's coming when I take a few days off in August!!
