As Mercedes began to replace models through the '90's, cost-constraints turned the replacement models into mere mortal cars (or sub-mortal, judging the severely tarnished reputation for quality in recent years). The W201s (190 series) are among the last true Mercedes -- built to a money-is-no object standard. The car is constructed with a tremendous and obvious overcapacity; it performs flawlessly and, after more than a dozen years, is hardly distinguishable from new. Don't kid yourself that this quality means a 190 is a cheap ride. They're relatively inexpensive to buy, but the maintenance and occasional repairs are very costly. Don't think about skimping on maintenance either.
Build quality that will never exist again; solid feel; high quality materials. The complete disbelief of expressed by any passenger or driver that the car can be this old or have this many miles.
Essentially irrelevant on a car that went out of production more than a decade ago. For those who think the car is slow, try rowing the transmission manually. It's still not fast, but you'll be surprised how much more lively it becomes if you let the engine rev a bit higher.
