Which vehicle?

[Marc_767]

Hello again, I need some help choosing a car for our 4-week roadtrip from NY-San Francisco. There will be 4 of us (all adults and kind of tallish) making the trip and everyone has 1 piece of luggage and 1 backpack.

I have had quite good offers for 3 different sized cars and now I'd need to choose one. They are: Pontiac Grand Prix 4dr auto a/c, Cadillac DeVille 4dr auto a/c and Chevrolet Blazer 4dr auto a/c.

Last one is obviously the biggest one but it's also the most expensive one, so what do you guys think, will we fit in the Pontiac or should we pay the extramoney and get the SUV?

Thanks in advance

Marc
