2008 BMW 335i purchase

I've been visiting bimmerfest for awhile now and first I want to thank everyone for all the knowledge I've gotten from here. I'm looking to get a 2008 e92 335i and I wanted to get some input before I go through with it. Here's the info:

CPO
18,528 Miles
Drive
6-Spd Manual
Sparkling Graphite Metallic
Coral Red Interior
Sport and Performance packages
Navi
Keyless entry and the list goes on. it's pretty well equipped

I just want to know what everyone thinks about the deal I'm getting and let me know if I'm missing anything.

Internet List price is $34,995
They're selling it to me for $33,500
$4000 down
6% sales tax
I qualify for 3.9% financing for 66 months but free maintanence expires Dec 2011. They offered 2 additional years (Dec 2013) and 4.94% financing for 72 months.
Payments come out to $520/month

I look forward to hearing opinions. Thanks for the help...

I would look to get lower than that. With those options/miles, I would think the wholesale price of that car is around $27k-$29k. The dealer should be able to let it go for $31k-$32k. Throw the HPFP into your discussion. That in itself has brought down the value in these cars. They're still failing.

Go to edmunds.com and get a "True Market Price" for the car with those options. That will give you a better idea of the price in your area.
