Bhai there is no issues at all, I have done that twice now from Meezan bank. I would advice you simple rule of thumb to opt for leasing. You should be saving 2x, where X is your monthly rental. So if your car monthly installment is 30k, you should be saving 60k at least in a month, this is to avoid any risk or issues. It is also preferable to keep the lease period as short as possible, 2-3 years should be fine.
However it is still preferred if you can buy car on cash.
