Think an RX8 will accommodate you OK, if you can find a PZ or 40th with the Bilstein suspension it will be even better for the track part of your jaunt.
Thanks for the suggestions - looks like the 330ci and the EP3 are front runners.
In regards to clio/TT’s I don’t fit in them comfortably, it’s very much like raising a family with 3 children in a bedsit - doeable but far from ideal.
