Are you asking about full size or intermediate? Lots of folks here are telling you what they got as full-sized.

These days I stick to renting "full-size" cars if the family is with me. I can't easily get kids, carseats and stroller plus luggage into a compact. (The last two "full-size" cars I've gotten have been Altimas; legally a mid-size car.)
