Disclaimer: I have signed an agreement not to tell anything that goes on at my dealership. Thus, all of this information comes from the previous dealership I worked at briefly, because I dont want to breach this agreement. Consider this thread as more encouragement to avoid letting a dealership touch your paint. If you ever get a service wash and vaccuum, id be seriously worried. They are given ~10min to wash and vaccuum a car, so it is getting brushed with probably a dirty brush head, being pushed hard. $50,000 black car, they dont care. Dealership protection packages have markup in the range of 1000%, using inferior products. Most everything that happens is affected by a lack of time, a lack of caring, a lack of good products, and a lack of knowledge. Common practices: Windows: cleaned first by being sprayed with a medium strength degreaser, then steel wooled with a very fine steel wool. If done properly, it actually works quite well, especially with sap/bugs, which it gets rid of super easy. However, if you get someone applying the degreaser outside, or leaving it for a few minutes, it is going to "burn" youre windows, and leave NASTY streaking, which is a bitch to get rid of. Also expect them to razor blade off the stickers from shipping with no lubrication, causing permanent scratching. Tires/Wheels: Sprayed with a STRONG (industrial strength, you dont want this touching youre skin) alkali degreaser, and wheels probably with a strong acid, then brushed by a stiff bristled brush, halfassed, that is already depressingly dirty. Not good for wheels and tires. Tire dress used is probably a cheap, pure silicone mixture liberally sprayed on, so yes, its gonna be on youre paint. That is also not good for the tires. Interior carpeting/seats: Halfass shampoo jobs are common. The vaccuum cleaner will only usually have one attachment, so dont expect the nooks and crannies to be cleaned. Dirty floor mats? They will be SOAKED with a strong degreaser, and then pressure washed VERY thoroughly, vaccuumed of all water, and left to dry in the sun. Effective, but not good for youre mats. Either way, your interior is probably left wet, and you will have to leave it with all windows down overnight. Interior consoles and stuff: Air compressors are wonderful things. Light degreaser + unlimited compressed air + shitty rough towel = a surprisingly clean console and dash. If the car is getting a detail, not a new car cleanup, they will probably LIBERALLY spray a coat of disgusting original armorall quality dressing over dash, doors, everything not fabric. It is greasy, and collects dust. Paint: Expect scratches, somewhere on the car. If the dealership is particularly shitty, expect glue lines from the shipping plastic. If you are so unfortunate to buy a car that has been on the lot, invest in a good private detail (see autopia find a detailer), because it is going to be swirled SO BAD. This is assuming they dont try to get them out, which is about 50%. If they do, they will handwax it using a crappy shit wax, and MIGHT orbital it off. This is already after a DIRTY mitt, or most likely a dirty brush wash, and dirty chamoix dry. You have wax in all nooks and crannies, and they wont get it out. If they do break out the rotary, expect worse damage. Speed is the name of the game, so everyone knows what that does. In summation, when you buy a new car, for the love of all that is wonderful, make sure it still has its white shipping plastic on paint, and dont let them take it off. Do it youreself, and get it ready for delivery yourself. If possible, try to apprehend the car before it hits the lot, (discuss with sales manager), so it isnt beaten on by lot boys/mechanics. That said, I do maybe 10% of these horrible things, because I simply have too. I steel wool and degrease windows, but I do it properly, and in that case it works ok. I pressure wash floor mats, because it works well. These things just save so much time that you are unable to do it properly, because you will get yelled at otherwise. Nobody cares, except the salesman, for a few minutes, and even then he has no clue what is going on.
