Well bro. in my experience, Khyber is way much more cheaper than charade to maintain, and i think it would be a comparatively newer model, so would also be trouble free. We have a 2000 model khyber at home, and believe you me till date it has not given us any trouble at all MashaAllah, never even stopped for once... just keep the car maintained properly and it may last longer than the owner himself can .. as far as maintenance, for example, i asked a mechanic about overhauling of khyber's engine and he said parts required are yours, and i will charge 5000 for the whole job ... thats just for an example of how much it can cost to overhaul a khyber's engine..otherwise, not even a single light of it has been required till date.. very durable and economical must i say
