If one were interested in purchasing a 25 plus year old diesel Benz (say 300SD, 300D, 240D) is it being too forward and cheeky to ask to do a compression check and to make the offer contingent on the results.

Does anyone out there see such a request as reasonable?? I feel it might be "pushing the limits" of reasonable behavior.

Were I the seller I would want some contingencies before I would allow anybody to invade my precious (to me anyway!!) engine.
