1) Wood screws. Stop being a cheap bastard and use the correct damn screw!
2) Glue. Hot glue, super glue, epoxy, you name it. If it's broke, glue it!!
3) Improper assembly. I picked up an Optima Mid that had left suspension parts on the right and vise versa. It also had the front shocks mounted on different holes on each side.
4) Over-lubing. I've found shock oil in diffs, motor oil in shocks, vaseline in transmissions and I swear to god...LOTION in a shock. It had a very distinct flowery scent.
5) Cigarette smoke. I always ask before bidding, but the times I don't, I get burned. I wind up having to quarantine said car/parts.
I guess these are my top five. Just when I think I can't be amazed, someone pops up and does.
