His ad was misleading insinuating it was build in 1967. His response to me via e mail was "Fu$k you"... just want the facts. He did not provide the engine number but I am sure it is original. he seems like a jerk to talk to
The seller has a very good feed back rating (100%) and has sold several cars on ebay and all his buyers 'sing his praises'. I never saw the previous listing that you mentioned but suspect the seller is not a 'real Montreal enthusiast'. Probably a 'ebay lister' for someone else or he is just speculating with this car. He mentioned the previous owner had the car for 15 years until his death, so he hasn't had it for long. The engine number is pretty hard to locate if you are not familiar with Montréal’s.
I've been a seller on ebay for a long time and it can get frustrating dealing with a lot of questions and scammers but he should have been polite.
