I have a 97 convertible and she always stays in the garage unless it's nice enough to put the top down and go for a drive. I live in southern Colorado, and even through the winter months, there are always a few days each month when it's warm enough to put the top down and go driving. Earlier this week temperatures were in the teens with snow, and by Sunday, it's supposed to be in the 60's.
I bought my Mustang last year, and suddenly I started to notice other Mustangs on the road, in newspaper, on TV, etc.
