Thanks everyone for welcoming me into CL......one thing that I need to mention is that color preferrence is very subjective, every body have their favorite color. My SC430 has 51K miles on it and according to Lexus record, it has been serviced every 5K miles at the dealer since it was 6K miles from 2nd owner. The reason the previous owner sold the car was that the couple moved to retired home and don't need 2nd car. The interior is in excellent condition and exterior too except several small dings in the door area. I replaced all 4 tires at American tires, they forgot to put in 1 Allen wrench screw on the rim(I have the chrome wheels with allen wrench screws on it) and it cost them $12.65 for a screw from lexus dealer (expensive screw), but the service is pretty good. I did an alignment on the car as soon as I replaced the tires and bought the lifetime alignment for $220(Hunter machine with a plate adapter that screws to the wheel studs), so I can do alignment every 6K miles free. I did wax the car several times to get rid of the swirls on the clearcoat but seems that it won't go away. I think I need to buy the professional wax with the buffer to clean it.
Also I just bought a car cover from Covercraft custom built with weathershield material, very thin and easy to fold it also dust and water won't go thru. I used that material for my truck and it keep my car clean after 2 weeks. They have a special sale right now for the the cover since new weathershield HP just came out, but only color black. You can look here if you need one....
