You may need a new short block. In essence, a new engine. $6k minimum. Probably more like $8-10k. Understand that your car may not fail for another 60k miles, if ever, but you need to check your compression. Have the mechanic do a leakdown test of each cylinder. You may be able to get BMW to pick up the repair, but no guarantees, particularly if it is a car with spotty history that has changed hands a number of times.
If the car is an automatic, the transmission probably won't last more than 120k miles. They are another notorious weak point. That is why the 1993-1995 740s and 1994-1995 540/530 are such a deceptively good value in the used car market. The transmission will probably set you back $4k.
To those in the know, a nikasil engined 540i automatic with a bad tranny is worth around $5k at most.
Also, the no airbag thing sounds very sketchy. Either they were pulled and sold from the car, or the car was in an accident and not fixed properly. Something tells me this car has a bad history.
I hope you got a hell of a deal on the car, because it sounds like you MAY have $10k in repairs to put it right.
Don't get too alarmed, but find a good BMW repair shop and figure out what you bought. It would have been a better idea to learn about these things BEFORE you bought the car, but you'll know better next time. Good luck.
