Hi CSNOW,
From my years of experience, the 210 body E-class ( 1996 - 2002) was the best car that Benz built in recent years. Either the 6cyl or the V8. Yes, 96 and 97 model 6's did have engine wire harness issues, and the 96 did have ign
switch issues. But if you come across one of these where these pieces have already been replaced, you're safe. Even if you do have to replace a harness,
the harness itself is not hard to replace, just a little on the expensive side.
(About $500.00 list. )
A close second is the 202 body C class ( 1994-2000) after 1997. The 1998 - 2000 with the v6 is a good car. Very few probs. Just keep an eye on the front crank pulley.

Now of course being a humble tech, I drive a Very clean '92 190E 2.6 with only 76k miles on it. I still have a soft spot for the old beaters !
Hope this helps.
