I test drove a 2007 BMW 530I today. I took the car to my car guy and he found it to have a leaking transmission. He said he could fix the problem. If I buy this car for $20,975.00 with 71K miles is it worth it and will I have problems with the transmission in the future?
A leak from the trans is most likely from the plug hsg for the trans electronics, there is an updated plug unit for this, also despite being a "lifetime fill" oil it theoretically should be changed at 120,000km (70 - 80k miles). so a new sump gasket, seal and sump plug would be decent maintainence at this point. be sure they use the correct oil for the trans however or else major shift issues may occur, even destruction of the internals of the trans
