No matter how much you try to educate people, they will always believe in hearsay.
Alhamdolillah I have had a Liana for 3 years and never had any issues like the ones you mentioned and the ones people scared me with.
One gentleman had the nerve to tell me after 3 years that "janaab aap nay yeh kia ghalti ker dee... Liana kay to barray maslay hein. This was despite the fact that I had told him I had no issues and had enjoyed evry day of ownership.
So, enjoy your ride and whenever you go on the road, be happy in the fact that you paid a lot less than other car's owners for a better peice of equipment.
