Oh - I'd like to also point out the obvious, but none the less important - these old cars aren't designed like the new cars (really?)- they don't have abs, airbags, traction control, crumble zones, etc etc. They do have a lot of horsepower (and torque) - so with that combination, it's easy to get hurt in one of these. It's a great car to have, but I wouldn't someone drive it full time. I know people here probably do, but all I'm saying is that you're taking your chances.
Have fun with it, learn how it handles and stops (try a panic stop in an empty parking lot), and drive prepared. Keep a good distance from the car in front of you, b/c these old birds don't stop as well as a new Accord!
Congrats on the car purchase - yeah, I just posted here recently, and got a ton of info right off the start. Great site!
