Replace your car or keep it: how to assess savings and technology before buying

You leave the petrol station, look at the charge on your phone and think it is time to replace the car. That evening, a video shows a vehicle negotiating a busy street almost by itself, and the idea starts to sound like a solution to two problems: less money spent on driving and less effort behind the wheel. But each of those promises needs a different kind of scrutiny.

To decide whether replacing a car makes sense, compare the expected cost of keeping it with the cost of the alternative, over the same period and on the same routes. Then check what would actually improve: family space, comfort, maintenance or assistance systems. You can make this decision without guessing next year's fuel price or betting on when software will reach Israel.

Before looking for a model, define what needs to change

Try describing an ordinary week with your current car. How often do you drive to work, how many kilometres do errands add up to, and is a long journey part of your routine or something that happens once every few weeks? Add the things that bother you: an uncomfortable seat, difficulty fitting a pushchair, tight parking or repeated garage visits.

Now you can separate a problem that replacing the car might solve from an expectation needing investigation. If there is not enough room in the back, you can check that yourself. If you want lower expenses, you need a calculation. If you want the car to make driving easier, you need to understand which system is offered, the conditions in which it works and what it requires of you.

Choose two or three improvements that are conditions for buying. That way, an impressive showroom car will not push aside a simple need such as easy access to your parking space at home. The car you already own should also be part of the comparison: get a professional assessment of its condition and expected maintenance, instead of assuming that keeping it will necessarily be cheap or expensive.

Measure fuel savings on your own route

As of 5 October 2026, the Ministry of Energy and Infrastructure set a maximum price of 7.77 shekels per litre for self-service 95-octane petrol, including VAT, effective that day. That is a fall of 50 agorot from the previous update. For your own budget, use the price you actually pay and the amount of fuel you consume.

The explanation of October's fuel price and the effect of the tax reduction describes the relationship between tax and the other price components. It was published on Kvishim on 28 September, before the official October price was known there, so its forecast is not the current price. It is useful for understanding the mechanism alongside the official update already in force.

To compare two cars, take the distance you expect to drive and divide it by fuel economy in kilometres per litre. In an illustrative example only, for monthly driving of 1,200 kilometres, a car achieving 12 kilometres per litre will use 100 litres, while one achieving 16 kilometres per litre will use 75. The difference is 25 litres, or about 194 shekels at a price of 7.77 shekels per litre.

That is a fuel saving only, based on the example's assumptions. It does not prove the deal is worthwhile. Fuel economy figures from a test or advertisement should also match your driving conditions as closely as possible. Compare at the same distance and price per litre, then see how the result changes in a less economical scenario.

The amount you add at purchase is only the start

A trade-in offer sometimes presents an easy-to-remember figure: how much you must add after handing over your current car. Ask for the new car's price, the amount offered for the old one and all additional charges separately. This lets you compare differently structured offers and see whether a discount in one place comes with a lower allowance elsewhere.

To calculate ownership costs, compare expected depreciation from today until the eventual sale date under each option. For your existing car, the starting point is its current value; the original purchase price is no longer the expenditure you are choosing now. For the next car, the starting point is the transaction price. In both cases, the future sale price is an estimate, and it is worth testing a less favourable outcome too.

Add insurance quotes based on the actual drivers, vehicle licensing, maintenance, tyres and financing costs where applicable. Check coverage and the excess alongside the insurance price. Do not settle for a general average for a model, because you need a quote suited to your vehicle and use.

At the same time, check the payments you will have to meet: a deposit, monthly instalments and a final payment, if there is one. In a calculation that includes depreciation, do not add the loan principal again as an extra economic cost. Interest and fees do belong in financing costs. This distinction lets you assess both value and affordability without counting the same money twice.

A car that suits your home must also suit the time you return to it

Switching to an electric car starts with checking where you will charge. Before relying on home charging, find out what installation requires and what the quote includes. If you depend on public chargers, check which are compatible with the car and located near home, work or a regular route, along with their rates and billing conditions.

Visit at the time you would actually arrive. Can you enter the car park? Is there a time limit? Can charging fit around shopping, or does it require a separate trip? Convenient availability on a map does not necessarily mean convenience in daily life. Waiting time and the journey to the charger are part of the decision too, even if you do not attach a price to them.

On the test drive, try to recreate part of your ordinary day. Ask for a route that includes a crowded street, a motorway and parking, where possible and safe. Bring the pushchair or equipment you regularly carry, and check the back seat as well. A good fit sometimes becomes clear when you try a small task you do every day.

If more than one person will drive the car, all regular drivers should check the seating position and controls. A car that suits one person may require considerable adjustment from another. It is better to discover this before delivery, while you still have a choice.

Technology overseas is not necessarily a feature of the car you receive

The discussion of Tesla FSD approval in Czechia and what it means for Israeli drivers illustrates why you also need to ask where a system is available. On 21 September, the Czech Ministry of Transport announced that it had recognised the temporary Dutch approval. It described FSD Supervised as a Level 2 assistance system requiring continuous supervision and readiness for the driver to take over immediately.

As checked on 5 October, Tesla Israel's Model 3 page states that FSD Supervised is not yet available in Israel. You therefore cannot infer from a video filmed in another country, or the name of a software package, that a car ordered here will perform the same actions. Even where the system works, the classification described does not mean driving without the driver's responsibility and supervision.

With any brand, ask for the specification of the particular vehicle and trim level you chose. Find out which features are active on delivery, what requires an extra payment and what is described as a future update. If a particular capability matters to your decision, ask for a written answer about its availability and conditions. A future addition without a confirmed date is no substitute for a feature you need now.

Waiting can also be a good decision

After gathering the information, return to the reason you began looking. Does the alternative reduce total expenditure, solve a significant usability problem or provide comfort you are willing to pay for? There is no need to present every upgrade as a saving. You can choose a more comfortable car even if it costs more, provided the difference is clear and fits your budget.

If your existing car meets your needs and the savings depend on optimistic assumptions, also compare keeping it for a defined period. This is not advice to postpone maintenance or ignore a safety defect. It is a financial option to calculate alongside a purchase, based on the car's condition rather than its age alone.

Before signing, make sure you have a clear transaction price, quotes for the main expenses and a description of the available capabilities. The decisive question is what an ordinary day will look like once the excitement fades: how much you will pay, how much attention the car will demand and how well it will help you get where you need to go.
