Thanks Paul for inputs. I am looking into repository pattern. I m though not clear on how to access IsHatchBack property or HasFootPedal. When I do "input.", I only see Color and VehicleType as available properties. Using interface as an input parameter to method,, I cannot access properties that are in derived classes. Am I missing something?

This looks like Active Record pattern, you may also want to take a look at Repository pattern for persisting data. If you prefer this approach you may want to make Vehicle abstract and add Save to the Vehicle class as virtual so you can override it if necessary in the classes which need to check properties before saving.
