I can hardly tell that my 1-35 on an enclosed trailer (1350 lbs) is
behind me with my Subaru Legacy. My wife's Toyota Corolla pulls it
just fine, but it's a bit slow on 3% hills.

A twin Grob in a Cobra trailer is noticable however, especially in
crosswinds, since the passenger car radial tires let it develop a
sway. I wouldn't think of trying it with the Toyota.
