We generally recommend having any vehicle regularly professionally detailed in order to keep the surface de-contaminated and properly conditioned to have an extended lifespan and withhold a like new appearance for years to come. Detailing should be a regular part of your vehicle's maintenance plan, we recommend having a Complete Detail done every 3-6 months depending on vehicle usage and storage situation.
This ensures all of your interior surfaces are free of dead skin, body oils, dirt, grime, and are properly hydrated and conditioned to protect from UV and regular wear damage.
Your exterior faces a daily barrage of contaminates from the outside world, iron deposits, road grime, UV damage, and even built up car wash products will cause the surfaces to become filled with this contamination. Often times its difficult to see these contaminates, however over time they will have a negative affect on your paint system and other surfaces. Removing these regularly ensures a longer lasting paint system and improved cosmetic appearance.
