I am considering purchasing a 1990 300E, however I don't really know much about these cars.

It has 95K on the odometer and generally seems to be well maintained. Asking price is $2700 obo. Is that a fair price?

Everything is working aside from the original stereo.

How reliable are these models? Engine or transmission reliability?

Any issues I should look for when I go check it out?

What kind of maintenance issues would I be looking at should I buy this car?

Here are a couple of photos from the ad:





Thanks for the help!
