Thanks guys, appreciate all the comments and help. I like the idea of $1000 as the purchase price, since it will cost 2K to fix it, but the owner might not like it
.
Jim the metalic sound is not the air cleaner bracket, which is broken also by the way. I hold it still but sound will not go away.
Sixto, it might be relative to 420 that it feel like slow to take off. But is deisel that slow, I can walk faster than that. But on a serious node you are right about PPI, and let some one try who knows the diesels.
I will agree on the clear coat part of the paint, I think it is repainted. But it was done very nice, the record part bothers me more.
All in all It would be a good car for $1000, couple of months and 2K will bring it back to they I want it.
Another thought is pass this one and find a car which has most of the work done and pay 3k and enjoy the ride, but then where is the fun of being DIYer :p . If any of you guys know some one selling a mid 80's diesle within 200 miles of LA, I would appreciate the info. Meanwhile I will keep on looking, unless the owner decide to give the 300SD for 1K but I would doubt it. But you never know if he is stupid enough to not put oil before a test drive, he might be smart enough to sell it for a grand. I will keep you guys updated.
Once again thanks a lot guys.
