I am not familiar with the Sparrowhawk or whatever this one is, but you can't carry two adults plus full fuel in a regular 150 or 152 let alone a heavy one. It would have to have wing extensions and an STC for high gross- makes no sense for the cost, just get a 172 and be done with it. And since you mention carrying baggage I assume you mean to go somewhere, but these airplanes are not meant for x-cty. The seats are crap, cabin is small, ground speed is slow, and the range is a few hundred miles.
