So, the Lexus basicly does not need a warantee as these cars seems to run forever ........Not knowing the in service date when the 03 bimmer  started in could have been the fall of 02...........If that was the case the 6 years could be up 12 months..........After the fall of 08 you are on your own......$3,000 transmissions etc , expect it.......Yes i am a basher on the realiability of these cars.........Unless the 6 years start after you buy the car...........Good luck.....
