Pointers when buying a C4
Thx
Make sure the windshield wipers don't lock together or go off the molding when they're on. Make sure the spray works too.
Test all interior lights, exterior lights, make sure the back up lights work.
Make sure the headlights work and the adjustable seats and mirrors.
Check the signals and hazards because the flashers can get stuck after 27 years.
Turn on the radio and make sure the antenna goes up.
If it is a manual, make sure that it goes into overdrive, and stays in overdrive. It will need to be running above 160 degrees in order to go into overdrive.
Check to make sure that the vacuum lines are not cracked or torn, same things with cooling hoses.
On the throttle body, there should be a screw that is capped off for adjusting the position of the throttle plate, if the cap is removed, ask why. People tamper with this sometimes to get rid of idle fluctuations but, an idle fluctuation means there is something wrong.
Make sure the check engine light is off.
Look underneath the car to make sure no one jacked a hole in the floor or the rear storage compartments.
Make sure you have your spare tire and your lug nut lock key!
Also, listen for knocks or ticks, and ask how frequently the oil was changed.
Then take it for a test drive and listen for clunks or looseness.
And most importantly, test to see if it has power. I know of a few c4s that don't have all their power that they used to have, and it can be a number of things. That car should do 0-60 in under 6 seconds, if it doesn't feel like 6 seconds, something is wrong.
It should not bog either when you accelerate.
And I'm sure other people will come in with some other tips for you as well.
Good luck and hopefully you'll end up with a nice c4!
-make sure doors close good and don't need a super slam LOL
-check to see if it's a glass or plastic top(look for scratches)
