Made the mistake about....... 3 weeks ago, 98 a4
Problems already:

Transmission control module fried,
Transmission now slipping because the tcm fried and did some pretty impressive/damaging things to tranny,
only one window works,
seat belts are all loose some stuck,
corner light fell off,
2 of the door seals leak,
etc. there is more

And ill own up and say yeah i should have inspected alot better, was hard up for a dd though and jumped before i looked. Will never make this mistake again
