If you do choose to sell your Z (I shake my head as I write this), don't go with the supra. Yeah it has back seats fit for grocery bags and golf clubs but not humans beyond the size of mini me. Like I think someone suggested an M3 is a good choice and the G35 coupe had some surprising room in the back seat. Think about this carefully though, imagine life without your Z and another car in its place... you getting teary eyed yet? The Z's shoes are big ones to fill. IF I were in your shoes I'd keep the Z and buy something used with some power. From where I stand selling my Z would not be an option. Just my opinion.
