My family and I are planning to go on a trip to Texas next week to check things out there and we are leaving from Oakland, CA. Anyways I have a big family so we were about to rent a 14-15 passanger van but it cost $1200 for a week and thats expensive. So now were planning to take my 05 4.4 X5 and my dad's new GL450 and we calculated that it would probally save us $600?? Mapquest says it would be around 27 hours of driving.. What do you guys think which route I should take?? the van or 2 cars?

Do you guys think that I should take my X for such a long drive?? Anyone tried to drive that long on their X before? Also I have around 12,000 miles on my car already and it would go past the 15,000 service by the time I get back home.. But I think it should be OK cause I just got an oil change 2,000 miles ago (change my oil every 5,000 miles with Mobil 0w40)

Also Texas is really hot and I was wondering will the Mobil 0w40 will be OK while driving down there? OK, Thanks everyone.. Sorry for the long post, Im just excited about the trip and driving my car down there..
