There are a lot of mods that can be brought to this motor to make it a true animal, a lot of MB guys swapped these to i5 or i6 Tdi's! Saw one this year on B-a-t with an LS swap :O
I wanted to buy one last year. even a 500 sec with the 5l. the ones i saw where 15k to 20k and I saw one 5k car that look like it had been sitting there for 12 years rotting away.
too bad cauz theyre great looking cars. I would have stanced that thing to death.
