Lease-to-own in the UAE question

How do people feel about lease-to-own offers in the UAE? I've been looking into them, but the information is so scattered. How does one compare lease deals in the UAE? Every dealer quotes a different "from AED X/month" Is there a tool or company?

I'm trying to lease a new car and every dealership gives me a different "from AED X a month" number with no breakdown. None of them show the effective interest rate or what I'd actually pay over the full term once you add deposit, mileage penalties, and fees. Is everyone just calling ten dealers and making a spreadsheet, or is there a smarter way?
