hot to cold

i have a question is it bad on a car that is normaly in cold climates (ie avg temp 50) to a climate that is normaly warm (ie avg temp 85)

No.

Nope. There is no difference (typically) between a car designed for delivery to cold climates than one for delivery to hot.

Manufacturers test the same car in Alaska and the Mojave Desert to make sure they're ready for anything from -29 to 130.

I think It was the TopGear winter olympics special where rich hammond drives a car into a hangar and drop it to subzero temperatures, seeing how it long it takes the running car to die completely, with hammond inside. Funny as hell but very interesting.
