The WORST Car for Bullrun?

After reading about the big rig, I got to thinking, what would be the worst vehicle to perform the bullrun reality series in?  Now before you start baggin' each others rides, I thought we could find out some serious bad choices. 

The car must be street legal as it does for the show.

Here is my submission. 

I thought what would be the biggest drawback?  Mileage? power? realiablility? Handling?

I came to the conclusion, manuverability.  Most of the other aspects can be overcome in a challenge if you rock it out.  But if you drive something that flat out couldn't 'handle' a challenge, well, you are S.O.L.

So how about a FWD Car that weights a ton and is 11+ feet long?

Other limos like the Hummer limo or Expedition limo may be much heavier and truck based, but at least there is the possibility of rotaing the vehicle with the gas pedal.

Hustle the DTS Limo into a corner and you can do nothing but increase the understeer.
