Short answer
New Mexico taxes vehicle sales at 4%, no local add-ons. New Mexico taxes the price after the trade-in is deducted. New Mexico credits sales tax legally paid to another state, so the same dollars are not taxed twice. This applies to a retail dealer purchase; lease deals and private-party sales follow their own rules in most states.

From the desk
New Mexico charges a motor vehicle excise instead of ordinary sales tax, at its own rate with its own rules. The desk quotes it like tax, the statute treats it like an excise, and the difference shows up in the exemption list.

Either way, collecting the right tax is the easy part. The title work, the temp tag, and the out-of-state registration still have to land, and Voltra's title tracking keeps each one aging in plain sight.
