Hello all. My newly acquired W123 Diesel has a driver's seat that reflects 313,000+ miles of abuse. It's ridiculous. I have never sat on anything so shot... except maybe a bean-bag chair in college. Anyway, I've been poking around on EBay for a seat. I have not been impressed with what I have found. My goal is not to replace this seat with another seat that is only partially worn out.

My question is twofold: 1. What is the most cost effective way to get the seat repaired?
and
2. Will any other chassis seat work in the W123 body?

Thanks in advance.[&:]
