Stiff sidewall tire in combination with heavier and larger rims.
Non-OEM suspension along the lines of stiffer struts - like KYB AGX.
Loose and sagging door hinges and rubber cover missing from door striker as a result.
Plastic dash pieces missing screws to hold things in place.
Aging plastics creating that awful squeak nose when they break loose from a position of rest against another similar piece.
As stated above, there are tapes by 3M for squeak reduction and even some of the push pins can be loaded with squeak reduction tape as they are inserted to tighten things back up.
If someone has been in there removing things, you simply have to check if they are tight, require a re-alignment or if you have wind noise from window felts or rubber surrounds that need some
building up where they grab the metal seams, to make for more compression against the door surfaces/window glass.
Sometimes you have bent A pillars and or B pillars (the main culprit), allowing the top back of the door to stay slightly loose against the door jamb.
This can require putting your knee at the mid point of the door *inside mid point where the door card meets the latch mechanism - just above that - and pulling the top of the door/window frame back until you have moved
it back into a better and tighter fitting position. This is of course assuming your hinges are aligned and tight enough to be working properly.
Those are the biggest gremlins that affect all cars that I can think of, but hey if the mid body spot welds are all popped, someone went Dukes of Hazard and not much brings a car back after that ... forget I said that!
Go grab it and put some love into it, if the price is right and car is solid. Be prepared for work, if any major components have been neglected for any length of time.
I think I wrote a book on what to look for on a fellow members post here recently. Areas of concern, what to look out for.
Oh, and welcome aboard ... almost!
