TCC’s Bottom Line
Aston Martin has developed the DB11 as a true grand tourer, balancing comfort and handling in a beautiful package that would make a comfortable car for an escape to the cabin many hours away. Beauty, power, and capable handling come together in the 2018 Aston Martin Vanquish S to make it one of the most appealing grand touring cars on the market. The 2018 Porsche 911 is a superlative sports car that has defied its age. It’s a classic, but performs better than nearly any newcomer to its arena.
