Rusting after 7 years? I drive a 15-year-old Taurus without a trace of rust, even where the paint has been scraped away. An how does an A/C rot away? At the very least, you need to get your local government to quit using salt on the highways; it does next to nothing for the snow, and eats through cars. Even still, with the freakish bad luck you describe, I think you need a witch doctor, not a mechanic. Eating a tranny at 75K and pissing oil at 45K is just bizarre. (I’ll presume you know how to drive and maintain a car, but the only time I’ve ever heard of a tranny going that young in the last 30 years was someone who didn’t know how to use a stick shift on a Geo.)
As for the Civic, I can’t tell if you’re praising your Japanese nameplate, or cursing your American-made car. 278,000 miles is pretty good for an alternator., and if you’re really putting 50,000 miles every two years, I can’t be shocked that brakes and shocks need to be replaced; that’s not poor workmanship, it’s inevitable wear and tear.
