Hello. my copen has been standing since 2016. I´m planning to start using it in the spring of 2021. It´s a 1,3 2007 model. It has done 40 000 km/ 25 000 miles. The garage is dry and ca 20 C. I started it today and it runs perfect. What should i replace before i start using it? The obvious thing is the battery. It´s dead. What else?
