I wouldn't buy one to support Ontario.
My first inclination would be to support a Canadian province but right now they don't build a car I want and I can't see buying an inferior car to support Ontario. If they build good cars, people will buy them.
If Chrysler quality goes up I would.....I have purchased Chrysler product in the past....
I wouldn't do anything I wouldn't normally do just to help out a province. I'm like you in that I would buy a Chrysler if it was worth buying and not until. I find the OP kind of funny. What would have been the reaction to a question like "would you buy a gas guzzling SUV to support the Alberta Economy" or "would you build a garage to support the BC Economy"?
Buying a car to support a provincial economy must be pretty far down the list of best reasons to buy a car. I would think that most people probably buy a particular car because it fits their needs, or it get's great gas mileage, or it seats six adults. My wife might buy a car because she likes the colour but that is no worse than all the British sports cars I bought because they cornered well or they just looked cool or the engine sounded great. Supporting the provincial economy would likely fall behind all of the reasons I mentioned.;-)
I'm in the market for a new car. I've decided a honda civic. Made in Canada, good gas mileage. Cheap reliable transportation...
