I had one.
Now its way too old bro. Dont go for it.
Its a very economical vehicle. But faults start to show up now. I had a hard time keeping up with it. As faults seems to pop from somewhere.
But, if you can fix the faults and keep it tidy, its very good option.
Dont compare it with alto. Accent is really comfortable. Also it has a very good boot space.
Most common fault is the engine misfire.
This is mainly caused by bad or counterfeit ignition coils and cables. If you fix a genuine ignition coil it should solve the problem.
Also, dont ever ask any sri lankan about a korean vehicle. They will never say good about it. I sold it and got a japanese, and still sri lankans had to say something about the kapanese too.
Always go with your gut feeling. Have some spare money on hand for rapairs if you are going for the accent.
Good luck.
