Looking for 06' Cayenne S and advice
 

Hello everybody!
After quite a bit of research I have decided to buy an 06' Cayenne S. I am looking for a clean Gray/Black one. I have the following questions:
[ul][*]Anything specific to this car to lookout for? (besides the obvious)[*]Any suggested upgrades to improve MPG like a chip or minor mods?[*]What tires work well for all around use? (winter & summer 98% of time on pavement)[*]Does the factory tow pkg include anything besides the hitch & harness? On U.S. cars you get upgraded radiator, battery, brakes, etc.[*]What is a good technical resource? At $200.00 for an oil change I will probably do the minor stuff myself.[/ul][sm=feedback.gif]
