What actually moves your quote: size, method, access and timing
Four variables explain almost the entire AED 30–120 range. First, vehicle size: a Yaris and a Land Cruiser are different jobs, and most vendors price SUVs and 4x4s roughly AED 10–30 above saloons because panel area, wheel size and interior volume are all larger; vans and seven-seaters sit at the top of the band.
Fourth, timing and frequency. A one-off Saturday-morning booking after a dusty week is the most expensive way to buy this service. A weekday slot, a recurring schedule, or two family cars in one visit all pull the effective per-wash price down — often to AED 25–45 on a monthly plan versus AED 40–70 ad hoc. When you compare vendors on tamam, which shows multiple verified providers with AED ranges rather than one fixed rate, these four variables are what you are actually comparing.
