Need some help, just bought a used BMW.

[Damon]

Hey, I am new to BMW's and cars in general, this is why I'm asking you guys for some help. I just bought a 1993 BMW 318is 5-speed manual for $2100. It has no real problems with it. I'll list some of the little things i need to fix.

-The sunroof motor is spotty, and works when it wants to.
-The window motor for the driver's side sometimes doesn't work, but when i hit it with a sizeable amount of force, it does.
-It has a lame, generic air intake, and i want to be reccommented to a good intake.
-Stock exhaust, I want to get a good-sounding exhaust.
-Both the driver's and passenger's side seats don't lean, I wonder if this is a fixable problem. They did at one time, but they quit working all of a sudden, for an unknown reason.

I want to fix everything, but I have very little money. I have about $500 saved up, and want to fix some of these problems. I could spend it all on an exhaust system, or some on intake and some on the motors. I have looked, and can not seem to find a place where I can get new motors and seats. Anyone care to help me out? I appreciate it,

Damon

EDIT: 150k miles, bought it from a friend. It is lowered, too.

How many miles does your car have on it? and howd you get it for that cheap?

It has about 150,000 miles, and I bought it from a friend.

You can try ebay for somebody selling seats. Seats from any e36 will work for you. You might have to settle for manual seats. They'll probably be expensive to replace. Try bavauto.com for new motors. Give them a call if it's not on the site.
