New 740IL ?!?

Have been shopping around for a used 740IL, Currently looking at 99, 2000 and 2001's. Best value seems to be with the 2000. would like to hear any input anyone might have on anything i might not be thinking of such as: options on a 2001 not on a 2000, 99 same as 2000 with same mileage... might consider a 750!!!
.
Also is the sport package only on the I? what does the Sport Pack have

i would suggest a 2001 7-series, bcuz it was the best of the 7-series before the 745......since there were a couple recalls on the car from 1997-2000, they fixed them all and made the 2001 the best of the 7-sereies, a 740i sport was my first car, and it sure as hell was well worth the bargain
