Hehe yes that's pretty much where I am now, although I'm starting to get over the 'grab everything' mode!
I started heading down that path as well, fixing up wipers on every car I find that doesn't have them as the rain in AC with CSP is just so bloody good! There's so many of them in wiper-less state though that I find myself having to start being picky or I'll spend all my time setting up wipers.
This is true, although of course there are likeminded players who'd agree on the same things (mostly). But yep, a public "these are the must-haves", as nice as that would be, is just unrealistic to expect.
Then again, there's good fun to be had in sifting through the myriad of cars and tracks, and one definitely develops a nose for crap after a while!
