1990 or 1991 Miata as a Winter/Snow Solo Car?

["Moore, John" <jmoore@spyglass.com>]

        So those of you who own or have owned a 90 or 91 miata, how would
one be in the winter? Would a hard top be necessary? I am thinking that if I
need to get a second car for winter, maybe I should get a 1.6 miata. That
way if the 1.6 miata turns out to be better in CS than my MR2, I'm already
set!
