Hoosier, the Miata will probably have more fun here than it does sitting in a garage waiting for the snow to melt. Even so, Miatas really shouldn't sit for long periods of time. They are cars that love to be driven.
Oh, I just found another good thing about Miatas. If the timing chain belt breaks, it doesn't destroy the enjoy -- the engine has a failsafe device so that doesn't happen. I was heartsick thinking my baby was now history because the belt broke last week. Towed it to Tri-County Automotive (man, I love those guys) and they said no problem. New belt, tuneup and all will be well.
