Yeah I got the same postcard about 2 weeks ago.
If I wasn't so freakin' upside down in my Sonata, I'd probably take up the offer for the $750 on either 2010 Fusion or 2010 Mustang v6 as a daily driver. Unless I can find a dealer that's willing discount their cars $2000 or so before applying rebates, that will never happen.
For Play: 2011 Ford Mustang v6 Premium Coupe w/Pony Package. Stock...for now.
For Work: 2011 Hyundai Sonata SE. The fun daily driver.
