Nice find!
Assuming that you purchase the Cuda, and she’s drivable, don’t concern yourself with the $10K that you may (or may not) invest in the Cuda. The $10K doesn’t have to be spent on day-one or even the first year. If you purchase the Cuda, you’ll probably have it for life, thus, upgrades can be spread along 5, 10, etc years. Most of my Cuda money & parts came from Christmas, birthdays, tax returns, etc.
I noticed on the dash, left hand panel. There’s the light switch, wiper switch, dimmer; what’s the fourth switch in the lower right hand side?
The fender code breakout doesn’t mention a rear defrosts or Rallye lamps and she’s not a convertible.
My humble opinion, if you have the funds, a place to store her (home garage), and she’s not your primary car – Go for it!!
