Hello - I am currently on my second W123 and am in need a second vehicle to pair with it. I am curious about the W124s yet my knowledge of them is very little. My first choice would be a diesel but I was also looking along the lines of a later model M104 car for the rite price / condition. I plan on finding a low mile / clean example of whatever I purchase. I am unsure of what years or engines to look out for. I think a 94-96 with the OM606 would be ideal but it seems hard to find a decent one.
