###### Abstract
Thus, we are witnessing a change of paradigm because there will be less demand for vehicles, but they will have to last longer, so the maintenance of the vehicle becomes paramount. This trend is also confirmed by the maintenance cost of electric vehicles, which is much lower than that of petrol cars. An opportunity is, therefore, arising for the aftermarket car industry (car maintenance, repairs, etc.) as vehicles will be responsible for more of the activity transforming the structure of our cities as well. Furthermore, according to the same report, vehicle manufacturers are gradually becoming software development companies to ensure that the needs of the autonomous car are met. In addition to this, the world of the connected car is carving a niche in the evolution of a more technology-based society in terms of mobility and smart cities. In essence, this change of paradigm toward longer-lasting cars will have an impact on the way people maintain their cars. In economic terms, as an average, and following the internal figures of Grupo Next Mobility Company, (www.gruponext.es) it is estimated that in the EU, a passenger car costs around EUR2000 per annum. Any variation below this would suggest significant savings for the drivers and for the environment, since better or reduced driving behavior leads to reduced pollution. Indeed, the revision of some basic elements of the vehicle (oil, filters, tires, etc.) helps to reduce the amount of consumption of the car itself, and, therefore, a well-maintained vehicle helps to reduce CO2 emissions [6]. In conclusion, embedding technology in the vehicle should be the catalyst for developing on-demand service models. By equipping cars with connected car technology, it is becoming easier today to control and determine how much a vehicle drives, how it is driven, what inspections it needs, or how much it spends on petrol when detecting the vehicle parked next to the gas station pump hose. This is a reality now and not only what is going to happen in the future. The emergence of the connected car, therefore, will help to increase the safety of the car and its occupants and will provide more efficient (in terms of cost and pollution generation) driving, being the prelude to future autonomous driving [7] and the transformation from the \"old mobility\" to the \"new mobility\". In terms of giving some context to the reader, the difference between a connected car and an autonomous car is that the first one reads the internal sensors and has connections with the infrastructure and the second drives automatically by sensing the surrounding environment and making driving decisions. As technology (car instrumentation) can play an important role for drivers, this article examines the role of introducing this technology around car expense management. For this objective, a participatory survey was sent to a group of experts (\(n=25\) at the beginning, but only 22 remained after the full study--thus, three people left the study or did not complete it in its entirety) and followed up with a Delphi method [8,9]:  
1. The objective of the Delphi method was to identify which determinants they believed had the highest impact on the money that drivers spent on their cars. Once these determinants were ranked by all the expert participants and an agreement reached following various rounds of the Delphi method, it was determined that technology has a salient role in forecasting drivers' expenditure on their cars, outperforming other determinants such as marketing campaigns or previous knowledge of the driver. 2. To confirm the outcomes from the exploratory analysis, a questionnaire was created to obtain evidence from everyday drivers. The survey was conducted to evaluate and compare the spending level of drivers who own a connected car with regards to those who have non-connected conventional cars.
