I have had my 300 for about a year. I love the car, but it is
starting to have some little things go wrong and I did not receive an
owner's manual with the car. I have NOTHING to go on. Tell me,
someone, is having my oil changed by a 'shade tree mechanic' something
that can be done with proper instruction? I have other questions, but
I will start with this one since it is my biggest concern.

to missysue:
My experience with my 300E was as follows:

After spending lots of money and enduring tremedous frustration using a
neighborhood mechanic specializing in European cars, I was advised to take
the car to a dealer with proper diagnostic equipment. "I WISH I HAD DONE
THIS FROM THE BEGINNING". The dealer has proper diagnostic tools
including mercedes computer access. The hourly rate may be higher,
however one hour with an authorized dealer is likely equivalent to much
more time with an independent, and the dealer's work is guaranteed. The
car now runs like a charm.

Good Luck

If you bought an older car and can't change your own oil you may be
hurting yourself. These cars at this age need TLC. It will last but
be realistic, a 20 + year old car made to last 5-10 years is
incredible and will take time, money and knowhow to maintain. I have
a 93 400E and its great but in a year I have put 1000 in issues into
it and I need to put 1000 more just to do a tune up. After the tune
up it will last 100000 miles so take your pick. New and coushy or
old and a great ride. 2000 in 2 years is better than a car payment
for a ride that was originally 58000 dollars.
