Any decently equipped challenger is a LOT more than 20 grand. A mustangs GT base price is around 35k and the Challenger is more expensive. They also weight like 4,400-4,700 lbs they're absolute tanks.
I agree overall though that most of the cars out there today are pretty lame with the exception of some really expensive European cars. The Japanese and American car companies need to come up with some clean, sleek, lighter sporty sedans and coupes.
Unfortunately the money these days is trucks, suv and crossovers. I doubt we'll see a big resurrection of sports coupes and sedans, it's a dying breed.
It all depends on what your definition of 'decently equipped' is.
I'm plenty happy with the 305hp that comes with the penta star v6.
Having the 460hp gt, i was also plenty happy with the 305 hp that is in the 2016 mustang we picked up for the wife. It gets around 27-30mpg at 80mph with the a/c on and a 14sec 1/4 bone stock.
Ordering a car with dealer options in many cases is throwing money away. With all the premium trim car options you can buy dealer takeoff 0 mile parts for dirt cheap. Heck, even fixing up the wrecked '16 there's STILL new take off parts sitting locally I've been buying for a fraction of junkyard to go on it. Don't want the 17" factory alloys? I can get 0 mile "gt" rims/tires/tpms for $400/set. Want the 'performance pack 19s it's 900/set. Leather instead of cloth get takeouts for $450/set front and rears. Strut brace $50. Lighted door sills $30-50/pair. Got a gt hood with built in heat extractors, turn signals, and wiring harnesses for $250. GT decklid with spoiler ran me $150 but was a 3hr trip to get the matching factory paint. And you've still got parts left to sell.
Yeah, a gt mustang is 35k but that's not really the conversation here for a super high horse car.... a 300+ hp base model is 26k msrp. Challenger sxt is 28k, gt 31k. ANY of those you can go in on a costco auto buying discount, stack incentives, and pay low to mid 20s on. Camaro I can't say because they're basically junk comparatively IMO, and I never would be buying one after having last looked about 4 years back. And that's with the stepdad having had a zl1 that's now downstairs in the garage. If I had to PAY for it, I'd go elsewhere (and did)
