Cost
Cost is the first and, perhaps, the most decisive factor to be taken into consideration before making any such decision. With leasing, the private car user doesn't have to pay the full amount up front, with the instalment amount being paid on a monthly basis. The price includes both insurance and any service or repairs that the car may need. These are costs that are added to the initial acquisition cost, which, however, should also take into account the resale value. So before you decide on getting a new car, it would be good to carefully calculate the money that will have to be spent in each case, taking into account all parameters and not only the initial cost, so as to calculate the real difference between leasing and purchasing a car, in the long run and not only initially, as well as the course of an investment such as a car over time, which usually depreciates in value quickly.
Flexibility
The flexibility offered by leasing is great, since users can choose for themselves the length of time they will use the car – in some cases there is even the option of a monthly contract – or whether they’ll be able to buy it after the end of the agreement. And herein lies the objection of leasing’s critics: the car does not belong to its driver. Of course, in this way there is no risk of the value of the car falling due either to age or accident. In any case, the decision must be based on your needs and what you can afford. In addition, if you like to change cars at regular intervals, then leasing may be an attractive solution for you.

Budget
As in any rental, so in car leasing, you must be sure that your family budget allows for the monthly payment of rent. This may seem an obvious thing to say, but it isn’t, given that the current environment is rather volatile, with inflation remaining at unusually high levels for Europe, putting pressure on incomes as well. At the same time, as mentioned above, it’s necessary to take into account other car costs included in the monthly rent, such as KTEO (MoT road worthiness test), road tax, service etc.
Fleet & Options
The fleet of cars offered for leasing is not inexhaustible. Of course there are many options, but there is always the possibility that you won’t find what you're looking for. This is a parameter that must always be taken into account before making a final decision on how you’ll go about getting a car.
For some, owning a car is a big decision. Obviously, it's not the same as buying a house, but it is nevertheless a substantial outlay. Accordingly, it’s essential that you to have a realistic picture of what you need and what you want. Study all the solutions in detail, do your market research, compare the data and choose the most suitable option for you.
