Very difficult to find for Mazda service. It's three buildings away from the Mazda dealership with…read moreno Mazda signage. The only visible manufacturer sign is Opal. The service writer was polite but didn't speak English. Very expensive for a routine 15,000 service: 420 euros. About twice what I paid in the US. Took twice as long, too. I'm not sure why a routine oil change and tire rotation would take especially long, but a lot of people who checked in their cars long after I did got their cars back first. I had an appointment. They said the service would take two hours. It was closer to three. They don't take American Express.
