Here is my contribution to the Challenger theme - one of the best looking muscle/ponycar in my opinion: Both are quick out-of-the-box builds without further detailing:
amt's 1970 Challenger R/T Convertible was built from the '79 Matchbox/amt release - molded in yellow, it got only a clearcoat.
mpc's 1974 Challenger Coupé was an annual kit I got from a pen-pal from Indiana in 1986. Impressed by the movie "Vanishing point", I sprayed it in white with a clearcoat and added the custom front spoiler - otherwise it is box-stock.
Built in 1988, the following 2 photos are from 2008:
Last winter, I sold both of them - whereas the Convertible was in a rather good condition, time has not been very kind to the mpc '74 annual: the clear coat showed very visible signs of yellowing - much more than in 2008, and the vinyl tires were eating up the wheels which were melting and showed kind of bubbles around the circumference - I cut these off as good as I could, but obviously those tire/wheel combos were not meant to survive more than 45 years...
Here are some more pics (this time from Dec. 2020):
