dude... don't even think about getting an AE86 as your first car...
a) they're rare enough as it is
b) they're WAY overpriced, and parts are rediculously expensive if you break something
c) About the only thing you have going for you is insurance (assuming its stock) - they don't charge TOO much to insure them (well, they didn't when i had mine anyway)
d) don't know about now, but when i used to have mine the cops had NFI what they were, but i assume by now they've pulled over that many wannabe drifters that they've got a bad rep and are targetted by cops.
e) They are not a good car to learn car control in for a beginner, as they are very twitchy, and will swap ends extremely easily if you don't know what you're doing with them.
as has already been said, please heed these guys advice: they know what they're talking about...
get a cheap car... maybe even a N14 Pulsar Q or Ti (they have a N/A SR20DE in them) or something like that if you dont want something TOO slow...
it will be an infinitely nicer car to drive than a clapped out stocker AE86, but it doesn't have the 'ZOMG look at me dorifto' factor.
Edit: also get comprehensive insurance, as it will help you later in life with insurance ratings etc, but you just have to be wary of what claims you make (i.e. don't make a claim for doing $1000 damage to the car, as they'll rape you for it... just pay the repairs yourself)
