DS7 crossback - servicing?

Hi all
Im thinking of buying a DS7 crossback, but note there are very few official DS servicing/dealerships. Is this a problem when you get issues that a local garage can’t fix? For example, with my current Volvo, over 10 years, very occasionally I have had an issue and the local garage has suggested I go to Volvo to get it looked at… and my nearest DS is a LONG way away, so would not fancy using a day to drive there. thank you for any advice.

yes it is…for diagnostics with computer, it’s suggested to go to an official dealer. Programming etc.
the other garages are not fond of doing something, especially if its electric related.
