He kept me informed and did a thorough final walk through.

Doug (Crew Chief) was terrific. He took some time to explain everything, asked my preference on several items and took time to make sure everything was level & square. Clint (Sales Consultant) was excellent. He kept me informed and did a thorough final walk through.
