I had a 911 in my youth and it was like driving a very fast VW beetle (the old one), noisy, cramped and you needed feet like a ballet dancer to operate the pedals, they were almost on top of one another they were so close. Don't get me started on the rip off price of servicing and spare parts, it was ridiculous. This was in the UK in the early nineties (insurance circa £500). As it turned out, they were'nt even that trendy as every yuppy in the city seemed to have one. I've never driven a Z4 but I'm a big fan of the bigger BMWs (7s and 5s), the 535i I had was probably the best car I've ever owned.......sigh!
