The decision to buy a car is a big one. For many it is the second largest investment of their lives and it can be emotional. Rule of thumb is to be aware of how many miles you normally drive in a year and if that fits within the mileage limits of the lease plan, then maybe go for it. If you are a high mileage driver, absolutely not because you will end up paying extra money when you give the car back at the end of the lease.
