Welcome Hogg, it's sounds like your looking for a used turn-key, your in luck as there are more seats than butt's to fill them right now, Aging out, Estate sales, etc.
Big Hp is not a problem now-a-days, just make sure you have brakes, suspension, tires to match your HP. I'm a 15" tire fan, just from the org. look's, plus nothing fits the bill better then your Cobra lighting up the tires @ 60 in third gear
As Tony said ask any questions, we're here to help, you have found a great group of knowledgeable gentlemen here. Maybe give us your budget, color wanted, 4 or 5speed, Small Block or Big Block, etc? We sometimes know of cars coming up for sale before anyone else. I know of a 2011 FFR Mk.4, with a SBF 408 (440+HP 500+ Ft. lbs. torque) TKO-600 5-speed, and a famous owner !! Let me know if you have any interest, by PM me. Cheers TommyRot.
