I've been working on converting my W201 Mercedes engine to a V6 3.8lt ecotec from a VX commodore for the past year or so. Some people will hate it others will love it. It all comes down to preference. I love the styling and comfort of this era Mercedes, but unfortunately the engine was a bit tired even after a full rebuild, I was spending more money on repairs than the car was worth, so i made the decision to keep the car which i use as a daily drive and change the engine to something a bit younger, reliable and economical to maintain. Being in Australia, what is more common than the good old commodores, they are reasonably well built and a dime a dozen as they say.
Turned out to be a great conversion, feels and drives great, looks completely stock but a total sleeper!

I will try to post up as much info and pics as I can for anyone who is interested.
