Your complaints. It makes my little my sister seem manlier.
just kidding.
I am in maine, we got ice snow and 60 degree south winds at the same time. Keeping the car from popping like a failing tin can (yes even an 87 subaru) has been my mig welded outrageous goal.
As far as extremes and the rest of america..it is easily prophecied.
I keep an eye on oils, new stuff. crazy dynamics is a must have defended in the oil. (I spotted castrol edge recently for example- synthetic is still a bit of a exxagerated falsity).
Struts lose memory in cold snaps, even high end brands...although..high end is still a better choice.
tires? go for extremely high treadwear rating, they grumble, thump and pretend out of balance sometimes..but all prevails again...
windshield wipers. they all suck. no matter what. I used to work on 707 airplanes...now there is some wipers I'd like to have...
keep waters out and vent with a trickle open...never shut the car completely. most trunk going sedans need not worry, hatchbacks however...
exhaust systems. holy cow. oem is a nightmare...
steel in general. it is fender guage in fancy shapes doing big work, successful in death valley and australia...everywhere else however...
and lastl, but not least..Fuel Injection Sucks.
