Last month, Chevrolet unveiled the 2015 Silverado Rally Edition appearance packages, just as GMC unveiled two special edition trucks with unique accessories, the 2015 Sierra Elevation and Sierra Carbon. These special edition trim packages offer buyers model-exclusive wheels and unique decals in addition to other cosmetic enhancements, helping to further separate their truck from the other GMCs on the road.

The good thing about these appearance packages is it increases the appeal of the vehicle and they are relatively easy for General Motors to produce. As a result, you can expect to see similar packages offered on other trucks in the GM stable.
