Nice-handling SUV. Steers much more sharply than my previous SUV, a Lynk & Co 01. Has almost the same options as the Lynk. I wanted fully electric, though. The Marvel has a realistic range. So far it has never shown the WLTP figure of 402. But whatever it shows, it achieves. And I've experienced that very differently before (Lynk & Co 01 and Mazda MX-30). In short, a very good, comfortable EV. Downsides: abrupt steering corrections and annoying warning beeps. These can be switched off, but you have to do it every time. It's also a shame that the otherwise great navigation has no Dutch voice.
