Funny, I was thinking that but thought, nah, he must know that car is HUGE! LOL. No worries. And yeah, we need a HO (AFX HO, not tjet) version of that specific car, it would be fantastic.
Not so much variants, as simply more (or less) patina on each car. There are differences in the yellows and blues but I simply buy them if the price is right. It's kind of luxurious to have 10 blue and white 43 cars. LOL. They may make trade bait in the future.
