I seem to be on a 89' auto carrier binge lately...been shopping around too. It seems there are three manufacturers making them - Con-Cor, MTL and Red Caboose. The Con-Cors are cheap (cost and quality-wise), come with "Vapido" couplers, look like they ride too high and the stirrups look like HO scale thickness: The MTLs are pricier, but the stirrups and ladders are nice and thin . Also, they come with both pizzacutters *and* low-profile wheels (they wear pizzacutter wheels but you can easily replace them with the provided LP wheels: The Red Caboose auto carriers retail for over $40, but they have amazing see-through side grill detail (in both standard and anti-vandalism panels), nice undercar detail and even come with your choise of enclosed or open door models. The stirrups and ladders, though, look pretty large in size. I was comparing the MTL and Red Caboose cars today at my LHS which has N scale only trains. The MTL cars look a bit smaller than the Red Caboose auto carriers for some reason. I decided to get two of the MTL cars because of those damn stirrups I like the panels on the Red Caboose cars, but maybe I'll order those online later on, as I was able to buy both MTL cars for under $75. Which auto carriers do you run?
