Lessons from my 91 Turbo:
-It's worth garaging it over the winter and only driving it from May-October. Taking the cover off the car, insuring it and flying around town in a car which people wont believe is 22 years old is most definitely rewarding after locking it up for most of the year
-Don't ever trust Vancouver weather; it will rain on the sunniest of days when you leave the tops off.
-Do things right the first time and avoid as many shady-garage-fixes as possible; I've had to deal with my share of shenanigans created by the previous owner
-Always keep original parts even if you're replacing them; be it body or mechanical. You never know when you'll need it or wish you hadn't tossed it out.
-Though I'm only 20 years old, you learn to resist the urge of doing things to or in your car as recommended by your ricer friends who's automotive knowledge peaks at their understanding of the fast and furious movies. I've learned a great deal about driving and respect for what is soon to be a collectors status vehicle as a result.
