I have a 250, so can't help you out there. But with the car itself, if you want 4 people to fit into it, comfortably, I'd say this car isn't good for you. Only because I've had people complaining (including myself, to be honest) that the back seat is small. If you want to put your grandkids in there, and they're younger, or you're just going for a short ride, it shouldn't be a problem at all.
I actually like the smallness of my car, but when I put one of my best friend (6'2") back there and drive for an hour, he gets cramped and I feel his knees in my back the entire time........
Thanks for the reply...
Actually my grandkids are quite small...one is 7 the other will be 3 this month so the space won't be an issue. Guess I'm wondering about the car after the "new-car smell" is gone. Do you like it as much as you did when you bought it? Any problem areas to be aware of? I've heard nothing but good things about Lexus but I want to get the scoop from guys that actually live with one.
The kids are small so this is definitly the car for you. I have had my 350 for almost a year now, and Iam still loving it. As soon as I get in I remember why I bought this car. Trust me, you will have no regrets!! Good luck with your search
