Re: Old Mercedes W140 S-Class : Restoring it vs junking it The W140 was pretty controversial when it was introduced. It still is to date. There are those that love it and those that hate it. Many of the latter ones ended up buying poorly maintained versions. And then you run into massive problems. The good news, parts availability is very good! But without somebody working on the car who really knows it inside out it is going to be a headache. I know quite a few very happy W140 owners that manage too keep theirs going at a very reasonable cost, once all the initial problems have been solved.
