Very bad impression of customer service. New car delivered with dashboard errors, dealership unable to fix the problem for 2 months, no response from customer service despite 4 messages... this scares me for what’s to come....

The Sealion is better finished and of higher quality. But it has higher consumption and charges noticeably slower.
