My 2015 Mustang GT had over 1200hp and a full interior. It could accommodate 2 adults and 2 kids just fine. I could build 3 of those for the cost of 1 Plaid, today, and it ran the 1/4 in 9.1.
But hey, I also don't build performance cars with luggage and kid hauling capacity in mind. And, if you don't think I can build a 9 second car for $30,000 you're smoking dope. I can build an 8 second car for probably under 15 grand. You can do some crazy stuff with a Mustang II body and chassis

. My '55 gasser runs high 9s, and including the car's value and all the parts I've put in it over the years, I don't think I've reached 40 grand yet. It can seat 6 on the two benches, no trunk space though. Fuel cell and battery kinda in the way.
Neither my Mustang nor the gasser has to wait 7 to 12 minutes for the gimmick mode to activate.
