Every Tuesday AM between 7:30 and 10:00 is a Cars and Coffee on the north east corner of Swan and Grant at the Starbucks, mostly old British cars but I show up there once and a while in a Porsche as do a few others. Good group of old guys meet there.
I second the Sonoran hot dogs and pretty much any of the taco wagons have great food that are found all around the town.
The Mexican food is very good In Tucson as a general rule.
Besides cars, Tucson is a great bike riding place. Lots of bike lanes and bike riding activities.
Mt lemmon is a great ride 26 mile ride up and the Saguaro National Mt. are great places to ride your bike or car.
As mentioned, Bisbee is a great destination for a overnight trip and there is good wine tasting at vineyards on the back roads through Sonita and Elgin on the way there.
Traffic is pretty bad during rush hour and it gets hot in the summer but no place is perfect.
Cars do not rust here but the sun will destroy interiors if not protected, shade becomes a must and sunglasses for you.
There will be some changes to the way you think. Many activities stop in the summer like track events, and starts again in the fall when it cools down.
Have fun and enjoy the trip and hope it works out for you to stay
