Used Mazda 2, not quite new but little km: Buy?

Hello together, have found online a used Mazda 2 with 90hp from 12/2015 with under 20,000km from 1st hand and with new HU. Looks also externally still top. Does not have a turbocharger, but LED headlights, which are known to be expensive in the repair. Suppose all (annual) inspections were made, should you access here after a check at the Dekra or can there be many repairs to me? Thanks in advance for your opinions.
