First luxury car: the running costs nobody quotes you

Depreciation is the largest single cost of any new car and it is steepest on premium models, because the used market discounts them for exactly the reasons this article exists. That is also the opportunity: buying a two to three year old example lets someone else absorb the steepest part while you get most of the useful life.

Then come consumables scaled to the car's capability. Larger wheels mean expensive tyres in sizes with fewer options. Performance brakes mean larger rotors and pads replaced more often. Air suspension, adaptive dampers and complex all-wheel-drive systems add components that simply do not exist on ordinary cars.

Insurance and repair labour also scale. Premium platforms carry higher parts prices, more diagnostic time per fault, and more calibration requirements after routine work. A bumper repair on a car with radar, cameras and ultrasonic sensors is a fundamentally different job from the same repair twenty years ago.

The way to buy well is to price the ownership window rather than the car: expected depreciation over your holding period, insurance quoted before purchase, a realistic tyre and brake budget, the actual service schedule with local prices, and a reserve for one significant out-of-warranty repair. Buyers who model that number rarely regret the car they chose.
