We’ve had a z4 for about 15 years and love it. It’s my wife’s car really but I drive it quite a bit. Never got rid of it because it’s aged really well and still drives lovely. Recently got a Porsche 911 turbo and at the moment I think the Z4 drives nicer. The Porsche is very slightly lumpy on tickover, has way too much power, things like the indicators are clunky and a few other little niggles that I wasn’t expecting with a premium car. Everything about the Z4 is really nice. It’s super smooth and the power comes in very nicely and has a decent amount of it. It handles really well. They are amazing cars and so cheap for what you get. I’ve wanted a Porsche for quite a while but the grass isn’t always greener!
