Keinreis stands for no in german because I have a huge passion for german cars, so I have actually read alot on this car. it is not silver, but audi a8's have aluminum sheet metal. so it was polished.
see specs from the creators below.
Created by German tuning shop and Audi specialist, Motoren Technik Mayer (MTM) for a client in Dubai, this MTM-tuned A8 also happens to be really really (really) shiny. The original paint was completely stripped to the metal (and plastic) using the finest-grained sandpaper this side of a baby’s bonnet. Then, the metal parts were polished to a high gloss, while the plastic parts were layered in a chrome-emulating series of paints and varnishes. Afterward, the 4.2-liter V8 was also tweaked to 450hp, a custom, ride-leveling suspension was installed and a set of really (really) shiny MTM rims were fitted.
