The car windows need to be checked for cracks. If you need to replace the windows, it’s best to get new windows from authorized auto glass shops. Polishing the classic car with chrome polishing products would ensure that it looks as good as new. All the rubber which lines the doors and windows should be sprayed with silicon spray so the doors and windows can operate smoother. The interiors are another important segment of the car which should be considered. Try to install brand new upholstery for the interiors and change the floor panels. Finally, you should try to restore the original paint color of the car to add more value to the car.
