Well remember All the JDMs like Mira etc in this range if any would have been driven in Pakistan for 3 or so years and might end up needing work. Atleast that is my experience with JDMs that are used in Pakistan for a bit.
And I dont think you can find a mira of that sort for 750k
Search alto, cultus and buy the cleanest one you find. In my experience for a used car condition is more important that anything. A bad condition mira vs a good cultus... The cultus is way better though an inferior car in terms of options.
For a used JDM you will probably get a beaten one for that price.
I personally think you would be better off buying a local car of these reasons:
4)Your Price range
Use it for 3 years, sell for a decent price and upgrade... with a Mira etc that would be problem since you would be buying an already used registered and beaten one.
