Both are out of these world cars... however... The k car is the real deal and doesn't weight 4000 lbs like the Bugatti. I still like the look of the F1 Mc Laren better. You don't need 1.45 mil to get er done. Just find a Ultima GTR car and put a TT SBC in it and you will have all you can handle in an ultra light package. 2200 lbs ? can't remember what it weighs. Their was a 1000 hp Ultima GTR at the Silver State Classic years ago but didn't go for the record due to fuel tank rules for the unlimited class. 2.2 lbs per hp will blow your mind !
