Exton automotive service station C&N Automotive has been in business since 1991. In the over 20 years there have been many changes to the way your car is serviced and maintained. C&N is a family owned, fully insured, service station for your car or light truck. Vehicle maintenance at C&N can range from a simple oil, lube & filter change to advanced computer diagnostics. As we all know the State of Pennsylvania requires a yearly safety inspection and anyone living in Chester County must have their car emissions tested. C&N is fully licensed to perform both types of inspections to be sure your car runs well and is safe to drive.
