The Audi A8 is one of the greatest rivals of Mercedes S-Class. It is beautiful and well designed with one of the top quality materials and a logical cabin. Its dashboard is equipped with a touch pad where you get to spell sat-nav with your finger. It comes with leather heated seats that are electronically adjustable and four-zones climate control. The cabin is up tops. Making Audi A8 one of the best luxury cars to go for.
