Back in 1991 a British Magazine "Buying Cars" contained a feature on buying used W123's. It is very well written and contains a lot of interesting information. I have had this article for quite a while now. The magazine was given to me by a friend and fellow W123 fan, Brian Levell who lives in Devon.
I recently discovered a fantastic document compression system called Dejavu. It is ideal for presenting brochures etc on the web since its compression algorithms are so efficient. So I have used this to put a copy of the feature (called "Soldiering On") onto this site. In order for you to view it you need to download the plug-in first. Having done that (it doesn't take that long) you can then click on the link below and be enthralled by this wonderful article written by a guy called Peter Lorimer.
Please don't forget the date it was written when you read the article. Some of the information is now obviously out of date. The garage mentioned in it (TM Motors) is no longer at the address shown. It is now located nearby at a place called West Molsey. Their (UK) phone number is 0208 941 4044. I have not used them so I cannot vouch for them.
