Moin people, I’m new in the forum and since yesterday also owner of a Smart 451 CDI convertible. I got carried away by a test drive with a Smart Roadster (was too uneconomical for me) to a Smart 451 CDI convertible. Normal no car I would have bought otherwise, my last cars were BMWs or Mercedes, well iwi it’s a Mercedes^^ It’s my first smart and my first convertible. The smart is in the Passion equipment, seat heating, light sensor, radio 9 , Bluetooth hands-free device ….etc. Built 03.08 70,000 on the Tacho. Since I would like to perform the inspections myself I wanted to know if you have a service plan, when will what be done and what is in the inspections on the plan. I also wanted to know what oil and how much the engine gets. Have read there is the possibility to exchange the original tub for an oil-screw, is the exchange itself to work out? About a service plan I would be very connected to you.
