Could you build this?
Partial The calculator UI is easy to build, but accurate out-the-door prices need current county-level sales tax, title, and fee data for all 50 states.
What it would actually take: A real version needs a structured, regularly updated database of state and county tax rates, DMV fee schedules, and trade-in rules, each linked to its source. The UI and calculation engine are straightforward. The hard, ongoing part is data collection and verification, which takes research staff and a maintenance process rather than engineering alone.
