You can also install that seat using the lap belt without the base, although it's a lot more difficult to get it to stay at the propper angle.

So you can either get another base and mount it in your 3rd gen, move the base between cars or install it without the base in your rig. If you're ever coming to Vegas feel free to holler at me, I'd be glad to give you a demo with a few different seats.
