Roadkill as in shoddily repaired cars ala WASTELAND GOODNESS.
It’s an entire Youtube series. Who knew.
So…
Junky Transmissions - Not all gears may work, limits top speed.
Zipties - A not all too reliable alternative for when you run out of duct tape.
Junky Electronics - Hit the brakes and the headlights go on. WHOOPS!
“Easy” to Fix Engine Failures - Car won’t start? Something’s busted or loose. Maybe you can jury rig the thing… temporarily.
Crappy/Faulty Brakes. Stopping may be a problem.
And on the flipside…
Custom Turbo - Know how a welder works? Got some metal pipes/tubes to work with? Are those… two turbochargers plucked out of diesel trucks? Oh SHIT is that thing gonna have some acceleration.
Plexiglass - Lightweight, fairly sturdy and pretty easy to get hold of. Beats riding around without a windshield… maybe.
Vehicle Part Reinforcements - You can reinforce just about anything you can pick up so why shouldn’t you be able to toughen up your vehicle too?
Improved Engine Cooling - Your hardware can handle higher temperatures. Higher safe speed!
Things like that.
