Not exactly "old school", but bear with me. Walmart has a couple of different scale Bronco R/C Broncos, the running gear is worthless Chinese cr*p, but they're cheap enough to pick up for the bodies, which aren't bad at all. I picked this one up (1:24 scale) for $9.99:
then removed the body and did a little work on it (removed all the stickers, trimmed the cage, the spare tire-ish bulge on the back, replaced the tube doors with full doors cut out of sheet plastic, and mounted it on a Proline Ambush chassis:
Still needs paint and some detailing, but it's a good fit for a scale crawler, and better looking than the Scout body that Proline uses for that chassis.
