*** BUYING A USED 1997 E420 WITH 20K MILES - I HAVE SOME QUESTIONS ***
First Question:
Besides the "usual" checks that you do when buying a used car, is there anything else that I should be aware of?
Second Question:
Would you do a pre-purchase inspection at a dealer or at an independent mechanic that specializes in MB?
Third Question:
It's a 17 year old car but with very low miles, what maintenance should I do as soon as I purchase it?
Fourth Question:
Do you have any positive or negative comments about this year and model?
Unless you want a bad taste in your mouth do a thorough inspection. Does the general condition represent a 17 yr old car or a car with 20K miles on it? I'd be pretty leery of such a low mileage car. A CarFax could confirm ownership. location, etc.
The E420 was replaced by the E430 fairly quickly. E430 was a better engine. But a well maintained E420 is probably fine.
I am paying a premium for this vehicle and it's more than a $1,000

The previous owner was a car collector and it was not driven much. The car looks brand new and it has all service records from the dealer. I also have the CarFax.
I am not sure why the E420 was only produced for one year. I believe the 97 E420 used the M119 engine that was produced from 1989 through 1999 and I read good things about it.

If it were me I'd have a MB tech inspect it and give you a written report. The report should include everything that was checked and the result. If someone isn't willing to do a written report then keep looking for someone who is.
Get a copy of the Maintenance Booklet for your model/year and perform all maintenance procedures starting with brake flush, coolant flush, oil and filter, brake pads and rotors, and transmission service.

BTW, don't fall for the low miles big premium price bit. This is not a collector car, and never will be. A small premium for condition is reasonable.

Transmission Pan - for debris
OBD scan - for pending codes
Test Drive - Accelerate to 60mph and panic stop - two or three times on deserted country road.

Is it absolutely necessary? No. Is the information it pulls up nice to know and have record of? Yes.
You never stated whether this is going to be a daily driver or not. If it will be, make sure to set aside at least 2-3K for repairs if you will not be DIYing, regardless of what the inspection shows. Add another $700 or so if the tires are more than a couple of years old. It would not suprise me if it has the OE rubber. Anything made of rubber degrades and deteriorates over time no matter how the car is stored. Suspension bushings, vacuum hoses, valve cover gaskets and breather, fluid filled motor mounts, shocks etc. The concept of a 17yo car with very low miles being trouble free is a fantasy.
It will be used as a second vehicle. Between 6 and 8,000 miles a year. I don't work on my own vehicles. You are definitely make me worried about my purchase ):
