audi GTs are usually pretty cheap and can be had for dirt cheap...saw a white one on ebay sell for less than 2k this last yr...looked pretty solid lol
i had a couple of 535i's for daily drivers...for the $4,500 ur thinkin about spending, you could buy a fine example and it would be a heck of alot faster/cheaper to take care of, although bring a couple hundred lbs of sand if you have deep winters
