I would just like to say that if you own one of these rare cars, and claim to be a collector, then please spend the 100 bucks to get it rust proofed. I rescued 2 of these cars from nitwits who were bragging about how much they love these cars, how they dreamed of them since they were kids, blah blah blah, only to buy one and not take basic care of it.
You're not a true collector if you can't manage something as simple as rust-proofing your car, before you go pretending it's a snowmobile. I am going to great lengths to preserve the cars I have, I thought about selling them off instead of getting the rust fixed, but I would rather not let them go to waste, as I know the next person wouldn't take care of them. Also, rust-free examples are next to impossible to find in Canada.
As a point of interest, there is a 100% rust proof ST185 in Ontario, or at least there was in 2018. I happened to have seen it in person, it was in car show condition. Too bad the guy needed to sell it right away, otherwise I would have bought it for sure.
