The original owner of my car put 3,200 miles on in 14 years

He pretty much used it for autocross racing (2 miles from home to where he raced) and maybe three car shows a year.
I on the other hand have been averaging about 2500 miles a year. I was closer to 3500 the first year and tapering off a little every year since. The original owner thinks i am driving the wheels off it.
I also live in a northern climate where the good driving season is four to five months. I pushed it occassionally to 9 the first two years.
