I have seen the 800cc version, the body is good, tough, but unfortunately wight comes with that. So it is heavy. And it is bigger than a Mehran, specially the boot after the cylinder had more space than mehran without it.
I would advise you to go for a 1050cc version if you want good value for your money. Primarily because the larger engine has the power to drive the heavy car, and it is EFI so it will consume equal or maybe even less than the 800cc engine.
I got my Cuore 2 months ago while I considered the Revo and did not buy it for the following reasons:
No auto option, the engine is chinese but I was not sure how easy will it to find a bolt-on auto trany and import from China.
The meter console is UGLY! Mr. Feroz Khan has acknowledged that and said it will change but now the question is WHEN?
I plan to swap my Mehran with a Revo 105 (A/C but non-CNG) when the new design is out, so that I have one family car and one commuting car.
