You would need to look around for a while / travel for the right car. The car isn't a 99 Chevy Cavalier where millions were made. There isn't much of a market for these big old barges making them a good deal.

Are you able to do your own work and to what level? I can fix anything so I tend to buy broken sub 125K mile stuff for pennies on the dollar and do preemptive repairs beyond what a running car is " worth " then proceed to get another 125,000 miles out of them.

There are a bunch on Craigslist in varying condition. Try to stick with 97 to 99 as it has the better ( electronic shift ) transmission. Regardless of where you buy, always have a reliable shop look at the car first.

Here are a few more.
Is in the "for sale by owner" section owner but I bet it is a dealer based on the pic. $ 2,490

Says needs injector, probably one of the 3 ignition coils / wires / boots have failed as this is common on this engine. $ 1,995 ( too much given it needs work. )

Says need transmission. There is a conductor plate that fails causing the trans to default to 2 nd gear. $ 525 , this could be a deal even it it needs a transmission. The salvage yard search site Car-Part.com--Used Auto Parts Market used ones sub $ 800. https://atlanta.craigslist.org/nat/cto/d/1997-mercedes-s320/6255528229.html
