I read somewhere that the 2002 TL has something like 500 changes over the prior model year. Only a few are listed in the brochure - memory seats, 6 CD indash, etc. Somethings are obvious like the wheels and the front and rear end. I assume that most of the 500 changes must be minor - if this number is even true to begin with. But, assuming it's true, does anyone know how to find out what these changes are? Also, when did front seatbelt pretensioners go into these cars - my brochure says the 2002 has them but Consumer Reports has dinged the TL in past years for not having them - I assume that the pretensioners were either a recent addition or that CR was wrong. Thanks.
