Since this is your first MB, you should definitely have someone who knows the brand look at the car. Pre purchase inspections can be relatively cheap (under $200) and should be considered a requirement for this model and these years.

If you are dead set on this model, you should find an example in the best possible mechanical condition because repairs can be very expensive. AC repairs are quite common and can run over $2,000. Check the maintenance records to see if the AC has been worked on already by a reputable technician.

Remember that they don't make cars like this anymore and you might be "disappointed" when you step up to a newer MB later on in life. Little things like the power INSIDE rear view mirror in this car will just amaze you but MB doesn't don't do that anymore. My '03 S430 has more base content than my '06 S430 had...go figure!

If I were you and wanted to get into the brand on the cheap but wanted something contemporary with a lower cost of ownership, then look for a good used E320 1992-1995. Classic MB body, strudy, readily available, easier to fix and maybe one of the best gas-powered vehicle series MB has ever made. I had two and loved both of them.

Good luck on your search!

Do your due diligence. To modify an axiom from the Rolls Royce owner's forum: "There is nothing more expensive than a cheap Mercedes".
