That's a bad ass car and it doesn't have a mortgage attached to it.
It's PAID FOR and is an ASSET.
At $40,000 new, then 5 years later and with $5-10K more in interest the 2KXX Challenger ends up costing $45-50,000. I wonder in what year, if kept under 70,000 miles, it will be worth 5-10 times ($250K- 500K) what it was when it was brand new? 2075? Ever?
Nice cars, I'm sure. They were novelties 4 years ago but I don't even notice them anymore (unless it's a cop behind me).
The only things I like about newer cars is AC and power windows and I can live without both or have them installed in my car. I save $35-45,000 and I'll be happier because you just don't see 45+ year old cars 5-10 times a day like you do the new Challenger/Camaro/Mustang.
As far as emissions go, I'm sure someone will come up with an exhaust gas recycling/reclaiming technique for us old skoolers in the next 5 years or so. Maybe even a ring, valve and ignitor kit that will allow our old engines to burn whatever organic snot concoction becomes trendy...
