there is a tech bulletin about resurfacing flywheels you may want to find i believe it talks about a noise and how to fix it. automatic car washes should be illegal! just kidding but they will mess up yoour paint every time with the plastic brushes.it may also be to low but i wouldnt try. most car washes also recycle their water and use an acid to purify it--really bad for the finish.the turn signal probably has a plastic stopper which is broken. i think you have to buy the whole thing to fix that but i could be wrong. good luck! im currently sorting out my own new 86 951 with 76000 miles.
