I have flown in an SR22 and it is nice but seriously "smashing her through the door in a 172" as I said I am a big guy way bigger than you and I have flown in an Aeronca Super Chief with 6' 200 pound instructor when doing my TW endorsement. Sure you have to forgo personal space (and a lot of fuel) but a 172 is really not that bad. The SR22 is going to cost 2X+ the 172 per hour but if you can afford it go for it.
It was a suggestion based on the size request. For the PPL the SR20 works just as well and is cheaper. The SR22, like other sleek and/or high HP planes, is a traveling plane. It can be a bit pricey for training or short "$100 hamburger" flights, but it's great for going somewhere.
