Hi. We have a VW Touareg that is not big enough for our 3 boys, ages 3, 2 and 8 weeks. Also, it breaks down more than it goes. Anyway, my wife doesn't want a minivan and we don't want a giant SUV. Also, we can't afford the LX470. Can the GX470 fit 3 car seats across? We use the Britax Roundabouts and they are 18" wide each. We don't need or care to use third row seating. Thanks
