Brilliant. So not only have you spent more money on another depreciating asset, but you've also bought a car that's actually smaller than the one you felt claustrophobic and camp as a row of pink tents in. I'm going to set up a BMW dealership near you, I'd make an absolute fortune.
Look, I'm only half taking the mick here and it's your money and if you're happy with the car, it really doesn't matter what I think at all. Hell, I spent a small fortune on the 911 and it's still a depreciating stone, but I love it more than anything else I can possibly think of. If you feel the same about a previous gen mid-spec Z4, then I'm honestly pleased for you. It's a funny way of getting yourself into a Zed though, you have to admit.
