Ford's initiation of the Quality Vehicle Modifier (Q.V.M.) program in 1990, was a pro-active approach by the company to help improve the integrity and quality of the Lincoln Town Car limousine conversions. Since Q.V.M.'s inception, the program initiatives and efforts have resulted in the establishment of numerous support programs such as purchase/conversion incentives, a fleet service hotline, Lincoln Limo Care dealer program, Extended Service Plan (ESP) coverage, annual Q.V.M. product/technical exchange meetings, credit assistance and advertising programs, and customer satisfaction surveys, among others.

Qualification for Q.V.M.. status for Coachbuilder begins with a stringent certification process. To maintain official membership and high program standards, Coachbuilder must pass an annual on-site evaluation by a Q.V.M. assessment team that includes an evaluation of the company facility, production processes, and consistent vehicle conversion quality.

A vehicle built to Q.V.M. standards has a Gross Vehicle Weight rating of 7100 lbs (standard Town Car G.V.W. is only 5400 lbs) and the Coachbuilder has tested and passed mandatory FEDERAL MOTOR VEHICLE SAFETY STANDARDS (F.M.V.S.S. required by ALL vehicles on the road) for each size of stretch length they produce. F.M.V.S.S. testing includes a barrier test, 135 break performance, 301 fuel system integrity, collisions in the front and rear, 208 occupant protection, collisions from front and side, and flammability tests. Cost for such tests are $75,000.00 in addition to the cost of the vehicle used for the test.
