With all due respect; you've bought a tin can. Why do you expect it to be something else?
Something called 'car'?
I can't believe we pay MILLIONS for this thing!
Anyhow, buy a white paint spray bottle and cover the peeling paint. Don't leave it like that otherwise your car's thin body panels will start to rust and rot. I've seen Mehrans leaking from the roof when it rains!
If you need a permanent solution; then get it resprayed. The whole paint has to be peeled off first with sandpaper which is very time consuming and hence will set you back a lot of cash.
Hope it helps!
