The B4 may have a better pedigree, but the Ansmann is cheaper and parts are plenty.
I think the mad rat is the best to go for if you are looking for quality with a good price to boot. Ansmann have good spares service.
TO my mind, any car will break if driven poorly.
This is of course if you buy new! Maybe a second hand car though is good to test the waters!
