are there mechanical differences between 126 sedans and coupes?
 

I'm thinking of something to replace the 91 300SE in 2003. The wife loves it so I'm thinking a 560 SEC won't be a radical departure. We have the SDL for when capacity becomes an issue.

Aside from pneumatic rear suspension and the M117, is there anything to look out for in a 560 SEC that I wouldn't be familiar with from managing my fleet? Anything overly complicated in the seatbelt extension arms or window seals?

Was there a 5-seating position option on the 560 SEC?

Thanks,

There very close. There was no 5 seat option. My seat belt presenters work great. If it rides hard it`s the air cells , easy to replace.
