I put mine away around Halloween usually. My daily has over twice the ponies and way more creature comforts, so unless it's top down weather, it's hard to justify dealing with all bumps and rattles of a 20+ year old lowered miata just to drive the freeway to work and back.
There are those rare bright sunny frigid days in the winter where it would be fun to bundle up and go for a joyride though....
Also, who tf is downvoting OP for posting a legit topic in a community that desperately needs the activity?
