What's different about buying in New Mexico

New Mexico charges a 4% motor vehicle excise tax — one of the lower rates in the country — with full trade-in credit. Albuquerque holds most of the inventory; for specific trims we frequently pull from Phoenix or El Paso and arrange transport.

Trade-in mathYour trade-in's value is deducted from the purchase price before tax is calculated. A $15,000 trade saves you $600 in tax here — which usually makes trading in beat a private sale once you factor in the hassle.
