The Mercedes-Benz GL320 BlueTec is a 7-passenger luxury SUV that runs on diesel.  The cool thing is that its fuel economy never drops below low 20's (and can be high-20's for highway).  Plus it has monstrous torque. 

In August 2009, Mercedes-Benz was offering a $10,000 dealer incentive to clear out the 2009 model.  In addition, through the Fleet Employee Program (FEP) that Microsoft is part of, there was an additional $2000 discount for any GL model.  Meaning, after you negotiate your best offer with a M-B dealer, show your FEP paperwork, and M-B will add the discount.

With the GL320 going for slightly below invoice, that meant:

•    MSRP:  $58,200
•    Invoice:  $54,126
•    M-B Incentive:  -$10,000
•    FEP:  -$2000

The base GL320 could be had for about $42,000.  That's $12,000 below invoice.  That was such an incredible price.  There weren't any GL320's for us even to test drive at our local M-B dealer.  But alas...I didn't have the $$$ to buy it.  Unfortunately, I don't think we'll ever see a deal like that again.

Update:  FEP is now at $1000, and there appears to be about a $4000 incentive going on.  But it's hard to swallow that knowing what could be had...
