I finally decided to trade in my '08 SLK. I loved that car, but it wasn't built for someone 6'2" 220. I've been checking online for a couple weeks and found this little gem, 2010 C300 with Sport and P1 packages and only 17K miles for $28K. It doesn't have the zip the SLK had, but it's much more roomy.
Got a decent deal. $1500 over Blue Book for my SLK (excellent condition, low milage), 500 under Blue Book on the C300 and financed thru MB for 1.99% plus my first two payments ($900) were made by the dealer.
