METHODOLOGY — what's verified, what's estimated
Cart price and kit prices are sourced and dated — the cart line says whether its price is the maker's MSRP or a dealer's listed price. Tax = 6% FL state + 1% county surtax on the first $5,000 (Fla. Stat. §212.05 / §212.054 — surtax varies by county). Fees = $77.25 FLHSMV new title + $225 one-time initial registration. Plate/annual registration vary by weight and county and are small. Delivery is quoted by the dealer — we never guess it. Your firm number comes from the named dealers in the quote step.
