Every brand with at least 10 vehicles in Roscommon, CC BY 4.0 CSO data. Share is of the county's total fleet, not of named brands -- CSO's "All other makes" catch-all (~1% of the fleet, many low-volume brands combined) is excluded from the ranking but counted in the denominator. Linked brands have their own page with the national picture and every county they're strong in.
