Sound like a lot of fun- until it's not! π Last year I took a driving course at Porsche Experience Center in LA - it was great getting to drive such a small and low car (911 C4S w/PDK), and having the freedom of a consequence-free closed track to explore the car's limits. I would similarly describe the 911 as having go kart like handling. Next time I go I'd like to try a mid engine rwd car (manual Cayman GTS) to see the handling differences between the two setups (over/understeer, recovery maneuvers, etc). Would love to get a smaller two door to have fun with, but the V70 just keeps on ticking and I can't justify getting rid of it.
Looking forward to seeing how you repair and improve the X1/9.
