Not too shabby to drive. My ex-girlfirend's family had a 1991 and a 2001 miata. The 91 was autotragic and could barely climb a hill. Also in the 91 I see over the top windshield which wasn't very comfortable to me having my head above it. The 01 man that thing moved. It handled well and rode nice.
Just be sure you don't forget about some of the practicality loss you will take. less trunk space only one passenger that sort of thing. I looked at miatas but decided I couldn't do it because I travel around too much and need the extra cargo space.
