good news is that if you go for a vrs it drives just like the gti.
however tbh if you don't have job security, and given the mess my two little ones made of the car when they were that age i'd say go for a shed. if i was doing it again i'd spend 5k on something like a saab 9-5 aero wagon - lots of room, kit, comfy, quick, cheap as chips and at shed money you won't cry everytime there is wee, poo, food, vomit, ribena etc getting spilt.
run that for a couple of years until the kids are past "that stage" then get back into something nice.
