If you are actually talking about the VW TDi diesel, we just bought one for my gal. Took 4 months to special order it and we just drove it home tonight. The V10 was about 10k more but for 553 pounds of torque, I think it will pull a boat just fine. (The diesel upgrades are not worth 25k in a boat though.)
Here's a picture taken with my phone about an hour ago.
