The one I bought Tucker cost around 40 dollars. He never tipped it over, he did however, escape from it twice. The first time I neglected to latch the zipper that closes the mesh panel and he dragged it down and got out. The 2nd time he escaped, he chewed through the rubberized mesh panel that looked very secure to me, in fact, I have my doubts that I would have been able to get through it with a knife or scissors. I never used it in the car, it was to be his crate here at home when I was out and he was alone.
