Everyone inspects the gas system. Few check what it did to the engine over a hundred thousand kilometres — and that is where the difference between a good buy and an expensive repair lives.
Locks and alarms are no longer the main barrier. Modern theft is work on the vehicle network rather than on the doors. How the risk is structured, and which countermeasures genuinely work.
The car calls the emergency services itself after a serious impact. How the system decides, why it sometimes calls for nothing, and what the dashboard lamp means.
The event data recorder captures a few seconds before impact: speed, pedals, seatbelts, steering angle. What is recorded, how long it survives, and who can access it.
A clean engine bay looks good and occasionally costs a lot. What actually suffers from pressurised water, why the problems arrive days later, and how to wash without consequences.
The most common electric car failure is an ordinary lead-acid battery costing a hundred dollars. Why it works harder in a car with no engine than in a petrol one, and how to keep an eye on it.
The additive shelf promises everything: clean injectors, raise octane, revive the catalyst. A breakdown by category — what has a physical mechanism, what works narrowly, and what cannot work at all.
On a modern car, jump-starting incorrectly costs more than a new battery. The connection order, why the last clamp does not go where you think, and when you must not jump-start at all.
Assistance systems that used to be premium options now come as standard on budget models. What they actually do, why they irritate in the first weeks, and what goes wrong with them after a repair.
OBD-II was invented to monitor exhaust. An electric car has no exhaust — so half the services lose their purpose. What remains useful, and where manufacturer requests take over.
The car updates itself with no workshop visit — and behaves differently afterwards. What actually changes, why your adaptations disappear, and how to record the version before and after.
Here you have everything at once: a combustion engine with a full emissions system plus a high-voltage drivetrain. And each half suffers because the other keeps working in its place.
