I think there's 2 Viper couples or more that run their child seat on the console, and attend Viper events!!!
Otherwise I'd buy a Supersnake Shelby GT with 725hp, or a Challenger SRT8, Jeep SRT8 and add a supercharger.
I 'helped' the wife buy an 08 RAM 1500 and am adding headers, exhaust, CAI, tune, etc. and will get 22mpg with 420hp. It is the wife's car and we do own a General store.
My 500hp 440 73 Duster has a backseat ane will appreciate over time.
My DD is a modified TT Stealth AWD. At 500hp I guess it's similar to a Porsche, except the Stealth looks nicer, gets 25mpgUS. and costs about the same as a Minivan. At 500hp it's only 11s in the quartermile.
