Beware of this company, as im now finding out they have been a hassle to deal with for years.. I recently ordered a cobra engine with a supercharge, it took these people atleast 3 weeks to ship an item they were to suppose to already have in stock... on the end of the 3rd week this guy name todd called & said, that your Mark 1 Engine is on its way.. I immediately said no! My receipt says a cobra engine, i refused the mark 1 engine he shipped. I asked for a refund, the only advice i got from them was to resell it on craigslist.com.. Im not in the business of buying & selling. They paid to have the engine shipped back to them. As of today they have my money plus they kept the engine... be Very careful this company Prestige Mustang Will Rip U Off!!
