You're talking about is the old Carburetor Mehran which you should sell it. You should go for the new 2012 model which has new engine that has the EFi.
In JDM Kei cars, I suggest you to go for Mitsubishi Minica, because it's available between 400-600k.
Speaking of these JDMs. Let me tell the truth about it.
In 1997, My father went on to buy a Toyota TownAce which was a JDM, but 4 years later that car started giving troubles and kept on getting heated constantly in highways. A/C also wasn't even effective as well and had to sell that troublesome car and went for Honda City. Since then it's trouble-free. That's why I don't suggest you to go for these used JDM cars. But still go for it, if you want.
