87 300TD What to look for

[Big Jim]

hello all, a buddy of mine who has no computer is contemplating the purchase of an 87 300TD. it is originally from california and spent some time in florida and is now in the chicago area. he looked at it yesterday and it had zero rust, a few small fuel leaks, pretty badly cracked dash, and interior needs a big time cleaning. 252K on the clock. sounds like it is in decent shape. what other things should he be looking for on this particular model. the guy is asking 5250 for it. my buddy is pretty familiar with diesel benzes but asked me to post this in case he overlooks anything on this particlar wagon. thanks....jim
