Suck-0-lux!
I've never had a new car before. The last 22 have all been old. Not "older", I mean OLD. And the fun thing about that was freedom to hack. The downside is hacking under-the-gun.
I think we need a /. for the car hackers. And not the idiots who glue on whale-tails (shitty ones at that) and call themselves boy racers. I mean people who look at a car's shortcomings and hack cool solutions.
EG:
Turning AND backup side-lights. (White lights on the front corner to light up at a forward-angle when turning, a backward-angle when reversing. Both sides light in reverse, btw.)
LED tail lights. Sure, the plug-and-play kind, as they pose some simple problems, but I also mean cutting them open and FILLING the suckers with LED's yourself. Personally, I'm becoming more enamored of 100w tail lights every day...
Stereos: but not the unlimited budget way. The brainiac way... (Example: I had a car with no cupholders, but 3 DIN-mounts for all the old stereo parts. Guess what? The 90-96 Ford Taurus had DIN mount cupholders!!! Presto: brainiac solution to a serious shortcoming.)
Lighting, interior. My back seat is so dark now you could hide a mass-murderer and the camera crew following him around. Would cold-cathode lights from PC-modding work?
Marker and side-lights. I've drilled into the front fenders to mount these before, but not on a car with a rust-through warranty. What to do? The Porsche trick:Put 'em in the front fenderwell?
See? There are a million of them. Every one would make a lawyer cringe and an SAE member bit their lips.
Cartalk can't be searched well at all. Car-specific sites are interesting, but wildly uneven. (boy-toy: Blue washer LEDS=cool. Old Farts: Mercedes coolant lasts longer. Cleetus' Cousins: Cow Magnets save $$$.)
I mean c'mon friends. So help me out here, ok?
