My buddy has a consummate "drove only to church on Sunday by a little old lady" car, a '97 Mercury Mystique with about 40,000 miles that recently had a bunch of maintenance stuff done. I can forward contact info if you have an interest.
I came on this post to link Dstrip's 2002 Taurus, which is listed on page 2 of this board.
I don't know him, but those cars if well maintained are bulletproof. And judging by his post, his is quite well maintained and low mileage. Hard to beat.
This is not exactly what you are looking for but If you are interested I have a 2000 mercury sable that was involved in an accident that I never fixed the damage. It runs well but does need some maintenance and there is no heat. I will sell it for $1,000. If your interested leave an email and I can send you pictures.
DPZ - where are you located? Please send pics to oldag92 at gmail. Looking for a beater for my stepson. Don't care too much if it has some cosmetic issues but it does need to be safe
Feel free to contact me for any information on my vehicles. I have about 70 vehicles on site with many that would fit in this price range. I will also include a warranty on anything you purchase.
