I'm the proud owner of an Mk4 LS 400 which is nearly celebrating its 10th birthday. (Although you wouldn't know it as it's in mint condition, with only 54K recorded miles) I have had the car for less than a month, and just updated the Sat Nav Disk, and will have to replace the FNS air dam which was broken when I bought it.
This is my first Lexus, and don't know why I didn't have one before now. I am constantly impressed with it's power and refinement, which has never been the case with my other cars.
Have been reading the boards for some time so I thought it time to join in and say hello.
