Smart cars are innovative and extremely fuel-efficient vehicles. If you have thorough knowledge of this vehicle and its parts, you may wish to service it yourself. When servicing your Smart car, keep in mind that the battery should be inspected and tested every 20,000 miles. The oil filter, engine oil, and wiper blades should be replaced every 10,000 miles, and the spark plugs should be replaced every 30,000 miles. Smart car servicing can be done with basic mechanical knowledge.
