I bought my 1999 Cadillac DeVille Concours in Reno, Nevada. It was a trust car before being traded in. It had 77,000 miles and now has 120,000. I have not had no problems except with a constant SES sign but the Cadillac forum tells me don't worry about it. It is a comfortable ride and a pleasure to drive on long trips. The only problem I will fix in the future is the oil leak that according to the Cadillac forum most Northstar engines have. I have changed the oil regularly, but have experienced no other real problems that have hindered my enjoyment of this vehicle.
I love the electric seats and back roller, Stabilitrac system, legroom, and comfort of driving without giving up power. I am 6'1" (214) and it is good for me.
A radar detector built in or a place to put the device. Underdash lights when entering and during driving if needed.
