In May of 2012 I decided to purchase a CLS 550 from Mercedes Benz of Sacramento, CA. After purchasing my car they convinced me to get cilajet paint protector and an interior sealant on my car. They promised my car would look better and it would protect it. So a week after I purchased it I brought the car in for the cilajet to be put on. I thought this would improve my car however, when Mercedes returned my car to me it was in worse condition than when I purchased it. The cilajet had very noticeably been applied over water spots and bug debris and that sealed contaminants into the paint. The creases also had compound in it. The inside of the car was done very poorly as well. It was not applied evenly and was different colors. The job looked like it was done by someone untrained for the job and lazy. After dealing with horrible customer service they agreed to redo my car a month later. The second time when the sealant was reapplied on the outside the bug debris made the clear coat cloudy in certain areas of the car and the interior was still uneven and spotted. I dealt with more poor customer service and they brought in an outside car detailer to attempt to fix it. He managed to remove the cloudy spots in the clear coat but the cilajet had buffer marks and scratches in it! At this point I was very frustrated and contacted the company Luxury Detail for an estimate of the repairs. Mercedes Benz of Sacramento refused to pay for any of these repairs and also refused to refund my money for the original cilajet which was done extremely poorly in the first place. The service was very expensive to begin with, about 3 times more than any other place would have charged and the quality was very poor. I now regret purchasing from this company. I wish I would have gotten the Jaguar I wanted to get instead because I heard from various people that they value their customers a lot more.
