Estimate: we don't have an exact county/city table for this state yet. The local box starts at the 4.99% statewide average local rate. Colorado home-rule cities, counties, RTD/CD and special districts all tax vehicles at your registration address. Why still an estimate: home-rule cities collect their own tax and special-district boundaries don't follow city/county lines, so a county/city picker can't give an exact rate; use Colorado DOR's address lookup (DR 1002 / tax.colorado.gov).
