Pretty strict – they check odometer carefully. Standard Ferrari rentals include 250-300 km daily. Go over and you pay 15-25 AED per excess kilometer depending on model. Adds up fast. When I rented from Octane Rent, limit was 250 km daily, charged 20 AED per km over. I planned route carefully – Dubai to Hatta round trip is about 200 km, left me buffer.

If you know you’ll drive more, ask about unlimited mileage package upfront – some companies offer it for extra 500-1000 AED daily. Cheaper than paying per-km overage. They use GPS tracking so can’t fudge mileage. Calculate your planned route before renting. Dubai city driving eats kilometers – Jumeirah to Marina to Downtown easily 50km round trip. Track it via car’s trip meter to avoid surprises at return.
