I am looking at a 1995 540i in Canada. 122,000 km (76,000 miles). BMW Dealer is asking 29,000 CAD (19,300 USD). He is currently replacing engine block due to the sulphur in gas problem, as well as putting in a new clutch.
Should the engine work be a concern or a bonus? How many miles should this engine be able to go without major work? Anything else (other than the normal things)to look for?
