old guy needs fun modern-ish driver

Grand National, 06-09 SRT8 Charger, 06-09 Charger R/T Daytona, etc. You can have a lot of fun in these "older rides". I have a 06 Charger R/T Daytona and it is a blast to drive around. It has aftermarket exhaust, intake and a couple performance chips and it sounds killer, runs like a SOB and gets thumbs ups everywhere we go. Tor red with HEMI graphics and all the interior comforts us old guys need these days. I'm 60 and enjoy the smooth confortable ride vs the smell the gas bumpy rattle ride our 66 barracuda is. Sometimes. Plus I drive the charger while I work on getting the barracuda ready for the road as the Charger always starts.
I dunno man if your 66 is smelling like gas and bumpy you can fix it, i dont remember my 70 dart riding bad when i had it on the road I thought it handled well. the charger yes i see them all the time flying on the highway i bet their comfort zone is 90 MPH.
I'm 63 and think the Mustang is a pain to get in and out of, the Challenger is better, taller roof line, Camaro is a Chevy, Chevys are something that you need to go to the doctor for. So I'd look for a Dodge or Ford 2WD short box standard cab and.spend a few bucks on it.
Yeah they are low to the ground you notice it when you are getting older.
