Not an E or 190 but I have a gray market 5 speed '95 S280. Can't wait to drive it more than up and down the block as soon as I put a good engine in it. I was originally planning on using an engine from a '94-'95 C280 but lately have been thinking of dropping in a '94-'95 E320 engine. The 3.2 would sure be quicker, but I think I may prefer a more authentic but slower feel of a 2.8. What do you think? Do they have the same bell housing shape so it would bolt up to the transmission?
