So, I finally bought my first car (my current car, an 89 camry, was handed down to me from my sister, who got it from my mom). Anyways, I've been working for 9 months to save up enough money to buy my car (I really wanted a 944 for the longest time, only to learn I couldnt really afford the maintenance).

Some info about my car:

1992 BMW 325i Blk/blk
150k miles (purrs like a champ though!) with recent radiator/h20pump change
5spd with leather MOMO shift knob
rear spoiler
kenwood sound system (10 cd, amp)
2 12" Bazooka boosters
Babied by a chinese UCLA PhD student

A few questions regarding the car.

1. How do i lock the doors!?!??! I looked in the manual, and it shows this thing that looks like the temp adjustment, but I can't find it!
2. Does the car come with an alarm? There's a little red light in front of the shifter, but I dunno how to activate and deactivate
3. How can i get more keys? I was given only the master key

The rear tires are almost gone. Any recommendations? Right now, they're 'charger' tires, or whatever. Thanks for all your input!
