Depends on how much you want to spend. I have 36" plastic VariKennel in my Highlander. Since I don't need any of the seats up, I keep it back from the hatch, but I think it would actually fit with the second row up. I'm not 100% sure about that though. And since I prefer to have the crate on the passenger side because it obstructs my vision the least, I can put up the smaller side of the split 60/40 2nd row seat without pulling the crate to seat 3 people.
At some point I plan to upgrade to a Rough Tough Kennel, they're supposed to be safer in case of a crash, and they're one of the least expensive options as far as the higher end crates go compared to wire or regular plastic. The standard XL size is around $300 until you start adding options like a second door, additional vent holes, or accessories. If you have money to burn, you can spend $700, $800, or even more on a really nice crate!
I recently gave away an older 36" plastic crate, the one I used for Halo. Cava came to CA from Colorado in a slightly heavier duty version VariKennel, so I decided to use that one in the car instead and rehome the old one. One of my teammates wanted it, so I brought it with me to the last practice. Here's a photo showing both 36" crates - I slid the old one in through the side door, the gray one is where I always keep it:
