never had any problems with the used car dealer I got my car from (Geoff Muir in Granville - he isnt there anymore)
A week after I picked up my car, I went in for a new radiator, weather strip, and new head light (not just the globe - the whole light!)
I mentioned to the guy I didnt know how to use the cruise control, so he taught me how to use it.
And for the next 2 years after that - I got Birthday cards off them, with scratchie tickets inside (I even won $5 once)
