Zoom out from the single visit and the numbers change. A weekly subscription at AED 100–250 a month is AED 1,200–3,000 a year — real money, worth judging against what it protects. UAE conditions are close to worst-case for paint: constant dust abrasion, salty coastal humidity, bird droppings that etch clear coat within days, and UV oxidation. Regular washing removes contaminants before they bond — the difference between an occasional polish and multi-stage correction at AED 150–400 per stage, or a respray beyond that.
The caveat: the protection only accrues if the washing itself is non-damaging — a year of rock-bottom washes with gritty cloths can leave paint worse than benign neglect. The goal is not the lowest price or the highest, but the correct method, done carefully, within the fair band of AED 30–120, on a schedule that matches where your car sleeps.
