I dont think I have had such bad luck with a car as what I have had with my 2000 Z3 2.3. I have only had it two months and it is already heading to the shop.
After having it a month, some lady backed into me in a parking lot. Luckily she hit my back bumper with hers, so the damage is minimal. Probably wont have to repaint the bumper, just straighten out some supports for it, to get it back into the correct place.
While waiting for the body shop to fit me in, I decided to go to Ziebart in Federal Way Washington and have them put on some Xpel. What a fiasco. First I get my car back, and they only did the hood and bumper. They said that they couldnt do the spoiler because it had to many curves. I said that it was part of the kit, and the said that they dont use the kits, they do it all by hand. So this means that they dont do the Xpel, like I thought I was getting. So I tell them to try it again and do it in a few pieces if needed. So I go to pick my car up, and they still didnt do it. I found out that they were actually cutting the film on the car. They tried to do the mirrors, and cut too deeply through the film, and into my mirror.
They did offer to pay for it to be fixed, and offered me a free detailing (like I would ever let them touch my car again).
I have since removed the stuff that they put on, had to make sure that there were no other scatches that I didnt see.
So two months into it, and I will have it in the shop. :(
