Under normal circumstances this is true. But research has shown that with the Millenium Yellow cars there was a phenomenon, much like organ rejection. For example, the paint cost extra because GM has to develop a a special primer that would not reject the yellow paint. Later they began to realize that other systems were affected. As I recall the "rev limiters" on the yellow cars often malfunctioned. Some owners were notified that they should purchase a fairly new anti-rejction drug known as "Sirolimus." Apparently GM recommended placing (2) 1000mg tablets into the gas tank on every fill up. All available data indicates the treatment has been successful. :L
