Will I use it more than the allowed lease mileage?
- If you do, it will be better to buy a car
How long do I want the car?
- If you only need it for a short amount of time, you should lease the car
How much do I want to spend?
- If the amount you want to spend is less than the cost of a car, than, you will lease a car instead
How much do I like the car’s options?
- There are more options when buying a car than when leasing.
hope this helps
The "will my family like the car?" is an opinion, and usually would not have to do with leasing a car. (and it also states that you have a family)
hope this helps
