dudes you can now see i found a great site that sale restored mustangs - http://www.mustangsonly.com/.. but they are too expensive for me, ive sent them a mail for the price of a fastback mustang 1966 and they say it cost 28,000$ its to expensive...
Ive also find in ebay a Bmw 850Ci- man that car looks great its got a v8 or a v12 th engine is 5.0 and its look great also from the inside.. and they are more chiper then then mustang- just 7100$... look at here http://motors.listings.ebay.com/BMW_...istingItemList
