I bought mine in 1977. Drove it a bit ( I had a company car as well and traveled a lot)- in 1985 it went into storage and as I was out of the country or out of the state I was delayed getting it back on the road - finally after 30+ years I decided to dig it out from the back of the garage.
Now I'm faced with re-registering in California as well as trying to get it a smog certificate. The engine in it when I bought it was a basically VW bug- single carb. I'm thinking of a new engine with dual carbs and try that, BUT apparently the 1977 VW engine was fuel injected and I don't know if I can convert easily (running a return fuel line to a new tank!?!?!?) or get the smog referee (a Calif DMV requirement for kit cars) to help get it done.
The Puma is a great car and very well designed - it is just in California the "powers-that-be" don't appreciate the classic cars.
