Go aftermarket DVD. You can get a way better systerm for about 30% of what the factory system cost. I have a link in my signature on how I have my system wired to the factory audio. It's hit and miss if yours would have the prewire. It can still be done by adding wires to the harness on the HU. At a minimum just hook the system to the AUX jack behind the dash and get a RF headphone setup....or IR since a lot of monitors already have it built in. The is a sticky on top of the interior mods forum with a web site that has great prices on AV equipment.cleetus said:

I would not go through the dealer for tires. Discount tire has done me good in the past but I've never changed out rims before.
I'd get an extended warranty. As many visits to the dealer as I've had for a spectrum of issues in the first year I'd hate to be without it after 3 years. I don't know if there is a package that takes care of maintance or not. If there is I bet you would save more doing it as needed vs all up front. Like at 7500 miles how likely are you to get an alignment done? I'd try to negotiate a year or two of oil changes and tire rotations.
