Good to know I'm not the only grammar Nazi. I've kept my grammer Nazism rather hidden, though, since it appears that any time I call someone out on their atrocious typing/verbal skills, I'm always greeted with the same intelligent quip: "YOUR AN IDIOT." (Which is ironic, because most kids over the age of 10 know the difference between the words "your" and "you're.")
Anyway, to the point: Sure, you could move down here to AZ, but be aware of what you'd be getting yourself into. For starters, your car has to pass a smog sniffer and visual inspection at least once every two years (usually every single year for me, owning two cars). This means no smog pump deletes, off-road H-/X-pipes, EGR deletes, etc.
Secondly, the evironment is just as harsh on your vehicle down here as it is anywhere else, only in different ways. No rust, obviously, because there's no snow (unless you go north to the mountainous parts), very little rain, and lots of clear, sunny weather, yeah. But even though it only rains about three months out of the whole year, you still have to maintain your car's finish religiously in order to avoid allowing a bright red paintjob to oxidize into a lovely off-orange or hot pink color. Carrying a California Car Duster in your trunk is mandatory; trust me, if you park your car anywhere between Yuma and East Mesa for more than 4 hours, you'll have enough dust on your paint/windows to make your car look like it's been neglected for a year. And with all the sand and grit on the roads at all times of the year, your windshield and front bumper fascia are going to be so pitted and sandblasted that you'll find it near-impossible to avoid looking at glass replacement and/or respray costs at least once every two years. (Rocks cracking windshields are an inevitability here, not an "if." Budget for it.)
Third, you have to accept the common risks of sharing the road with Snowbirds (75+ seniors spending their retirement money by travelling down here in the fall/winter and heading back north as soon as the temps go above 100 again) and many, many, MANY illegal immigrants with no driver's licenses or auto insurance. Additionally, said Mexicans do have a tendency to favor hit-and-runs - far better to destroy you n' your car and leave you hanging than risk getting caught by La Migra.
Fourth, even though the total lack of humidity means that air conditioning in your car is actually not as necessary as in, say, the Midwest, you will nevertheless become quite acquainted with what it means to nearly suffer an instantaneous heat stroke when you open your car and plop into the driver's seat on a 114-degree summer's day. Tinted windows, window shades, a white paintjob, and/or keeping the windows rolled down a tad (or all the way, even) will do little or nothing to spare you from the blast furnace treatment. And, of course, imagine what that kind of heat does to anything plastic or vinyl inside your car ... namely the dashboard.
Fifth, gas always tends to run at least twenty cents higher per gallon than anywhere else in America (except for, of course, California), and we put the worst idiotic additives in there. The MTBE crap they use during the summer months is bad enough - yayyyyyy, cancer! - but the ethanol they blend in there for the winter months means your gas mileage and horsepower start to take a dump.
And lastly, two words: URBAN SPRAWL. If you're worried about putting a lot of miles on your car, then I'd suggest buying a second vehicle if you live here. Someone a long time ago decided it would be really awesome to develop this place to hold about the same number of people as, say, Saint Louis or Chicago ... but to spread it all out over an area about as large as Rhode Island (maybe larger, I dunno). Unless you like dishing out about a grand per month for renting some dinky lil' condo or apartent that's conveniently located in the middle of some happenin' area like Scottsdale or Tempe, then expect to waste about an hour of your life round-trip in trying to get there and back, dealing with some of the worst traffic known to man. Practically everyone I work with has AT LEAST an hour's drive EACH WAY to/from work, somewhere around 30 miles each way. Since I only go about 150 miles before I need to refuel, I have to gas up at least three times a week ... and that's not counting running around for errands, shopping, socializing, etc. My gasoline "bill" runs me about $80 a week on average. If you're running an AOD with 4.10's and a blower ... ummm ... just don't.
So ... still interested?
