What to look for in a benz 300 td 82-89 diesel??

I am looking to purchase a MB 300 td turbo diesel. I have seen one that looks pretty decent. Some people suggest getting a PPI, where should I get this? at a benz dealer? a german car shop or a diesel mechanic?
also what are the most common things I should be aware of besides rust?
are 300td from one year better than from another?

what are the common cost for maintaining a car like this? for example brakes?

I am also thinking in converting it into a vegetable running car and also biodiesel. Couple of people have suggested putting a second tank on the car to extend the life of the car, how easy/hard is this? approxi how much would it be?

thanks for any suggestions.

YES, if you are unfamilar with a MB,
get a PPI. I would look for anything pre "85" after that, they went to the 6cyl......not nearly as bulletproof IMHO.

There are significant differences between the 82-85 123 TD's a later models. You should decide which problems with which you are comfortable dealing. Many people here prefer the 617 engine in the 82-85 TD's. Later engines have aluminum heads.
The hydropneumatic suspension on the wagons is the cat's meow but can be expensive to repair if major parts fail.

It also helps to be mechanically inclined, so you can work on your own car. Save lots on labor. Parts are not as expensive as some are lead to think because it's an MB. There are some parts that are expensive, like ACC, cruise control parts, etc. Brakes, filters, engine cooling, drive line parts, etc. not so bad.

newb.

Despite what some people say, you will not be bankrupted if you can't do the work yourself. Any job that would take me over 2 hours, I usually send to my indy. The trick is to find an independent shop that's reasonable, knowledgeable, and honest. Usually you don't hit it on the first try.

Think of maintenance as your car payment towards a longer, more useful life. I've had my 300d for less than a year, and had alot of bugs to work out. My initial $2,000 purchase quickly turned into a $6,000 investment total, but now she is close to perfect. I expect this payment to be at least $100-$200 average monthly now that all the bugs are worked out.

What price range are you looking at? The cheaper you go, the more likely you are to bury yourself in deferred maintenance like I did.
