Considering a 1987 560 SEC
 

Not sure if this is the right place for this post, let me know if not...

I've found one local to me for a bit less than $3,000. Listing shows the motor was rebuild including the top end about 80,000 miles ago. Suggestions as to what I'm getting into, what I might see repair wise in the near future (assuming it has 200k plus miles on the car itself). What are issues these typically have? It's my first foray into MBZ ownership (My dad has owned a number of diesels over the years), but this has always been one of my all time favorite cars. All input is appreciated!
