OK! thx for all the great feedback. With all of the wisdom from previous owners, I will not go down this rabbit hole. I'm choosing to play with a euro w123 wagon and a 73 w108. As much as I love the look of the coupe the M110 engine is too foreign for me and the floors need too much help. I'm selling it on craigslist or eBay. I figure someone could use it as a parts car. I think the manual tranny and bumpers are good for something.

Thanks again for the feedback!
