I don't know how much interior room your looking for, but if your talking about enough room for your wife and kids plus plenty of room for bulky stuff then I'd look into getting a midsize truck like the new 4 door Frontier or Tacoma
1. These new "midsize trucks" are bigger than ever.
2. 4x4 plus all terain tires
3. Towing capacity.
4. Truck bed plus a roof rack, anything goes.
5. easy drivability.
6. It's a truck! super versital
I convinced my parents to get an 07 Frontier last winter and since we've had it the whole family, friends, relitives love it. We do alot of boating/fishing, snowboarding, shooting, ect. and it's very handy.
Just to give you an idea of pricing, we got a 4 door, 4x4, Nismo package, with all the good stuff for 20K used. Still has the powertain warenty, but I do all the maintanence and it's a breeze.
if your interested let me know I can show you some pictures and give you some info.
Oh, doesn't buying a new car suck?
