re: The Wildest BMW M5 Ever Created Is a Wagon With a McLaren V12

The BMW E34 M30 engine was virtually indestructible and very easy to work on. I had an '86 535, '89 525 and a '95 530. The 530 was a slug unless you had the 5 speed manual. BMW ended up giving all of the 530 owners a new engine because the original small Nikasil V8 failed prematurely due to the high sulfur fuel here in the US killing them. I think they replaced them with an Alusil engine.

I loved my slug 530. I had all the weight of the V8 with none of the performance of the 540 big V8.
