ebennz - I had the same problem with my 126 and for years I wanted to put new springs on. I was going to have an upholstery shop do it but they wanted $1300 ($700 parts, $600 labor). Last summer I couldn't take it anymore and I bought a pair of new springs and pads off of ebay for a total of $200 including shipping. It took me about 3 days for the whole project (that includes and entire day of vacuum and shampooing the carpets).

You should give it a shot. Best thing I ever did for my car.

BTW - I'd say it's about a 4 on the difficulty scale and I consider myself an intermediate DIYer. Good luck and let me know if you need any help.
