Freaking tight bolts. :P Changing the dogbones on my E32, one of the bolts was off the scale on my torque wrench (reads to 150 foot/pounds) and still wasn't budging.
Luckily I remembered I had a 4 foot long piece of pipe floating around. Slipped it over a breaker bar and it undid, but was still tight. Whew!
Also jacking up my E32, what a pain in the ass. The car is so low that there was only like 2 inches between the jack handle (fully down) and the fuel tank. Prick of a thing to jack up the rear of the car.
