    GAHH occasionally needs local vehicles for test fitting of new products we are developing. Our free pattern promotion program is offered for specific vehicle models and only vehicles which the car owner will deliver to our North Hollywood California facility and leave with us for 3 to 7 days. We typically require up to one week to perform multiple fit tests as we fine tune the fit and appearance of new products. Occasionally however, it may take a little more time depending on the complexity of the new product we are developing.
