You mean Mhz scopes.  From what I know, 1Mhz would be fine for all
automotive work, that is so long as you don't mess with the internals
of the computer, then you probably need 20Mhz-100Mhz+ depending on the
clock rate of the computer you are dealing with.  Most automotive
inputs are pretty low frequency, in fact so low that .5Mhz may be
enough for auto work.
