I have seen on other forums that the 1981-1985 Mercedes 5 cyl is the best for durability.
However, I see that it is also a little doggy on take off.
I heard it sometimes takes 2-3 seconds to get moving?
Who can tell me more about this and can it be zipped up with some add-on hardware (i.e. bigger turbo etc.)

I would appreciate any and all info.
thanks
