I think another reason the market for big(ger) scale kits is limited is space. How many of us have room to display 10-15 big scale models? I don't have room enough for all my 1/24 - 1/25 cars, most are packed up and put away.
I'm working on one of these right now, stalled as I anticipate foiling . Yours looks great! What kind of problem did you have with fitting the interior?
Beautiful model. I also like the chrome steelies. They were the wheel of choice if you couldn't afford "mags" back in the day. I bet it was fun foiling the drip moldings! Nice work.
