SIt now takes two hands to count the number of production supercars making over 600 HP, which means it’ll take at least 400 more HP to guarantee permanent one-upmanship against the Joneses. That's where this eBay find comes in. Sure, the starting price of $229,500 is a bit steep for a Ford GT, but you’ll be bidding on a car equipped with the best interior of any vehicle yet this decade. Oh, and there’s the Hennessey twin-turbo conversion that nets “1000+” HP and 865 lb-ft of twist. All that power is good for a 235.4 MPH top speed — but probably not a 7:26.4 ‘Ring lap.
