Hey Garry,
The original blackfoot, mudblaster and monster beetle has red chassis and horizontal rear shocks on a cantilever. All 3 of these are the same except for the shell, but the monster beetle had oil shocks and gold wheels - very bling.
Newer generation Blackfoot was on a more sporty chassis (and I think was than named the Super Blackfoot), which became the generic chassis for Tamiya trucks - and the Monster beetle, Mudblaster, Lunchbox, Pumpkin were all ended around that time.
Id have another original Monster Beetle if they re-released it.
I always liked the Lunchbox, just because it was a van, but the chassis never seemed quite as good as the Monster beetle. Not that it really mattered when I was 10 and bashing.
