I have actually used L&N on many occasions; including building a new top for my Porsche Speedster, Installing a new top on my BMW 330ci Convertible, reupholstering a couple of motorcycle seats and reupholstering the interior of my aircraft. They are currently rebuilding the side curtains on my Daughter's Jeep. They do quality work in a timely manner at reasonable prices. Who cares if they are "Not a qualified member of a professional group?".., Whatever that means. I would recommend them to anyone.
