The best part of buying a CPO car is you can go for test driving and get it inspected thoroughly. It also undergoes proper maintenance and required repairs for a refurbished look. A used car is purchased at a particular price and includes no repair services. In addition, CPO vehicles come with warranties, insurance, buy-back guarantee, attractive installment options and many more. These days, CPO cars also offer roadside assistance – a great feature that is pretty common in brand new cars.
