lindberg makes some 1/35 cars, my LHS had a bunch last time i was there

Actually the scale is 1/32.  Not many kits available in that scale, but you might try some of the slotcar sites as it's a very popular scale (I have 5-6 of the little beasties).  Scalextric does sell its cars in the "white" or no markings.  These would be curbside kits but their full up cars are fairly well detailed for the scale.  There are also aftermarket bodies and decals (do a search for Pattos Place) If small stuff is your thing, come on over to the darkside and build 1/43.  You'll have a much better selection than 1/32, unfortunately you'll pay 2-3 times as much.

no, I'd build in a larger scale ( I hate anything smaller than 1/48 airplanes, no figures or cars) but need '35 scale cars to fit the figures I've started building.
