I haven't heard of a stock 426hp TT. Unless it's a SMZ or SR-71 TTZ. But the SMZ I believe have under 400hp and I don't believe it could be a SR-71 because those are very rare and I think over 500 Hp (not sure). The salesman will say anything too get you to buy the car. Have the car checked out by a mechanic(compression and leak down test). Otherwise the price is alright, but you can always try and get it lower.
