Nice rebuild! Looks like you had a very decent base to start with & sounds like it didn't need much to complete.
The B2 & B3 buggies really don't seem to be as popular as their older brother with the ali chassis, or even the Losi XX of the same era as the B2/3, but the B2 especially is a rare car these days (many got converted into B3s).
Will be interesting to hear how you get on with racing this notoriously 'lively' buggy
P.S; there's something about your paint scheme that makes it appear like something you'd see in an episode of Casualty!
