I am on the front end of my 1st Benz diesel quest. I purchased Kent's book "Mercedes Diesel Buyer's Survival Guide". What a great book. Probably the best money I will spend on this quest. To make a long story short, I am hoping to end up with a SVO diesel for my 150 mile a day drive. Believe it on not, I have found a "little old lady" with a 1980 300SD. She is the original owner. I am going to look at the car. I know there are some mechanical issues (climate control, cold starting). She has said to make her an offer. Does anyone recommend a ballpark figure? As I will need to reserve part of my budget for maintenance and repair. I plan to follow Kent's checklist and take to Mercedes mechanic, but just not sure of a "fair" starting point.
