My other 80s hobby is cars - I'm really into weird 80s sports coupes. So far I've had a 1982 Toyota Corolla notchback coupe that had been converted to TE71 specifications, a 1988 Mazda Capella C2 GT-R coupe (that's a first generation MX6 if it were NZ new) and my long running hobby car of choice, the Pontiac Fiero.
I currently have a pair of them, a 1987 SE V6 coupe, and a 1986 T-top 4-cylinder coupe. The SE is my weekend runabout, while the T-top is something of a very long term restoration project.

The V6. It's also got the personalized plate 'HAXX0R'...


The T-top before it went into the garage for metalwork.
So what other crazy 80s hobbies does everyone else have?
