Hi, I'm fairly new, was looking for new ride to replace the aging cadillac now that we are pregnant again and I want a decent sedan that is good on the highway now that I can't afford to fly anymore. I found a 1991 300E, supposedly with the 2.6 engine. Trans has been replaced already and some of the electrical work with 115K on the engine.
a. is this a decent buy for ~2500
b. is this a decent car with the 2.6 and can I cruise at 70-75 without issues? or is the 3.0 better?
c. anything I should look out for?

There is also a 97 320 that I found too, but need to talk to the guy first as he's only asking a little over 3K for it and it looks in good shape. Says it has rust, but i don't care about looks. I need something to get a year or 2 out of at least and something I can do some small road trips in.
Any advice I know you guys are great.

Thanks Paul
