When a tow is unavoidable, the equipment matters. A flatbed carries the whole car on a tilting deck and is the safe default for everything: automatics, AWD and 4x4 vehicles, low cars, accident damage. A wheel-lift truck raises one axle and tows on the other two wheels, which is cheaper and fine for a front-wheel-drive car lifted at the front, but towing an automatic or AWD car on its driven wheels for any distance damages the transmission. If your car is an automatic, and most cars in the UAE are, ask for a flatbed by default and mention anything unusual: lowered suspension, a roof box, a basement extraction, a car that cannot be shifted out of park.
Distance drives the price. A within-city flatbed move typically runs AED 200-450 depending on the emirate and hour, while inter-emirate tows, Dubai to a Sharjah workshop, Abu Dhabi to Al Ain, run AED 350-600 and up for the long legs. Decide the destination before the truck arrives, not during the drive: the workshop you trust, the agency if the car is under warranty, or home if you want time to compare repair quotes. A tow to your own parking followed by a considered workshop choice is often cheaper than an urgent tow to whichever garage the driver suggests, and drivers do suggest.
