Constant faults with the touch door opening, the trunk, sign-reading and the front obstacle sensors. The service repaired it under warranty five times — they replaced wiring harnesses, a sensor, uploaded software — and then gave up. They told me they don’t know what else to do. That’s the customer care at a German premium brand. A car worth over 400,000 and they tell the customer they don’t know what to do. I paid the final installment and I’m giving the car back to them. I’m taking a Chinese BYD Seal U DM-i plug-in hybrid with better equipment for 165k after a discount from 225k. With that attitude to customers and those high prices, the Germans will have fewer and fewer people interested in their cars — but they’ve only got themselves to blame!!!

BMW Z4

The BMW Z4 is a taut, road-hugging roadster that pairs elegant, low-slung styling with a roof you can drop on a sunny whim, delivering that pure, wind-in-your-hair driving thrill few cars manage to match. It’s an ideal weekend companion for drivers who prefer engagement over practicality — bring good shoes rather than a lot of luggage, and you’ll get a grin every time you turn the wheel.
