1999 E430 sport package

[voz1]

looking to pickup a 99 E430. Spoke with owner on phone and did all carfax stuff. Car comes up clean owner claims to own a lube shop said car got the best of everything & looks it. I was so impressed with online pictures and owner chat that I put off a trip (2 hr ride) to a dealer to look @ 2000 E430. So here's my question: The 99 has a "Sport Package" and I was wondering what this option included besides the oblivous nicer wheels. Also anyother input about pitfalls I should look for tomorrow would be helpful. Thanks for reading my post. Ed
