Goofy is the most polite word I can think of for the new motorcycle, minibike and bicycle models. Don't like them at all.
I like the new truck model. Hopefully some day they'll use a truck engine, and not a lawnmower engine to make it move. Still that same terrible audio.
The plow front end is a nice idea, but it seems it's more bounce over the zombies than plow them aside.
Edit: forgot the gyrocopter. That's the worst of the new models.
