I don't think it's a bright idea to buy a used Liana, even if someone give it to you for... Free.
Reason?
Well, since I can't seem to figure out how to put it more delicately and respectfully; I'll just say it out loud:
Liana is a heap of junk.
My uncle bought this garbage of a car about a decade ago and let me just say that this car proved to be a total NIGHTMARE for him. The build quality is poor, the reliability is pretty much nonexistent, the spares are expensive and for some reason; this car is a mechanical nightmare; even for experienced mechanics. My uncle's car stayed at a garage half the time and according to him; it's impossible to clock 300 kilometers in a Liana without running into some sort of problem.
This car, my friend, is a bad car, full stop.
But it's your money and your car so... I don't care what you end up buying. I won't even pretend!
I just consider it my moral obligation to warn people of trouble, for the better or worse.
Come to think of it; probably worse...
