Automotive sales. The outdoor display of new or used automobiles, panel trucks or vans, trailers, recreational vehicles, all terrain vehicles, motorcycles, snowmobiles, mobile homes or boats shall meet the appropriate yard requirements for the zoning district in which such use is located. Uses that are normally accessory to such sale establishments, such as engine repairs, body repairs, painting, radiator repair and undercoating, shall be permitted, provided such uses are clearly incidental and subordinate to the principal use and further provided that such uses are conducted within a completely enclosed building designed and constructed to minimize noise, fumes, vibrations and glare. Where an automotive sales use abuts a rear or side lot line of any district having residences as a principal permitted use, a solid wall or substantial, attractive fence six feet in height shall be constructed and maintained in good condition along such boundary. Outside lighting shall be directed away from adjacent properties.
