700-4 for sure, we have 10 grandkids and have had a few in the 700 a couple times. The rear seats with a fabric rear panel and the nets all latched. At least that way no on ecan lean over and fall out. This is ONLy done in the yard! If over 5 mph then the belts have to be buckled. My grand kids have think the (Sparky) pioneer wont go if the belts are not buckled.
