Well decided this morning to call the local Caddy dealer on a 04 XLR black that I saw on the floor when I was servicing my DTS. Decided to reduce my stable so I traded the 05 Mustang GT with 1300 miles that I picked up last November and my 02 DTS. Now I have the XLR and my 91 Deville spring time. The wife has the mini van and 57 Chevy with 36,000 original miles. So far I'm getting familiar with all the features. Any words of wisdom or tricks or short comings I should be aware of?
