I go to Montreal, all the time, and have a lot of connections there as well. It's nice, but you wouldn't want your cars on the roads out ther, come winter time with the salt etc. It's a beautiful place though. I hope you can learn to speak the language, but a lot of them speak english pretty well too.
They are about the nicest, and horniest bunch of people I've met on this side of the pond also. I'd love to live there for these reasons, and many more. I speak both languages fluently though, so I don't have too many problems with communication myself.
I don't know what advise to offer you though, in reguards to your cars aside from that though.., sorry.
