Danwellc I have an early one (1700-something) and have had no problems other than the radio which I replaced with an Alpine with XM; this gives me fantastic performance ( I must remember to turn the volume down with I turn off the car. Maximum db first thing in the a.m. scares the water out of you!). My dealer had a $5,000 discount when I bought. At that price the car is fantastic. I've since added Crystal Guard.
