BMW '83 533i Info

[bmwm3gtr200]

I found a 1983 BMW 533i in great shape for $900. Before I buy it, I am trying to find out what some of the areas are that I should keep a close eye on with this car. I am a fairly well skilled mechanic and have already looked at all of the usual suff(Engine bay, no leaks, little rust, very clean interior, no rust on shock toweres, etc.). Any common wear items that are known for this car would be great to know before I put it up on the lift.

Just to satisfy your interest, I know nothing about the E28 533. As you indicated you your other posts, you have already found the answer to your question. I welcome you to share your newfound knowledge about E28's and I will gladly add it to the sticky above where I have buyers info on the E39.

I used to own one but an automatic.
1. Check the engine seals for leaks (esp. the front ones)
2. Let the car idle and watch the temps. Old BMW's are notorious for overheating!
3. Control arms. (bushings are prone to failure)
4. Michelin TRX's. (metric tires, very hard to find and expensive to replace. You will have to buy new wheels)
5. Cylinder head gasket tends to "sweat" not exactly to the point of leaking but indicates a problem down the road.
