well, thanks for the advice all but i dicided to let this one go.

instead i found a 350sdl 233000km absolutly mint, no surface rust under the doors or anywhere near the doors. the car spent most of its time in florida even though its a quebec car. the IP was rebuild by the only certified silverstar rep in quebec. tan leather, engine is much faster than the 300sd which apeared to be blowed even as the seller of the 350sdl explained how the 300sd's degenerate which was he exact case with the one i was looking for.

underneath the 350 is little to no rust around the welded support beam. no rust around the lower door seam. all in all this car is great, plenty of pep etc... one of the this the owner told me is you fall in love with a car early when no repairs are needed. kind of sounds like something someone one this thread mentioned.

so basically chris from frybrid was correct, you fellas are correct.

now this 350sdl costs $11500 but is willing to sell for $9500 for a car with 150K miles.

i tell you the engine is spotless but that could have been cleaned but the fuel lines have not salt at all, just like new, the ip shines. i should take pictures and post them. its actually the owner of the dealership's car.

at this point what do you guys think?
