bro, liana is a great car - believe me, it is very impressive. santro se bohat behtar biult quality, drive, space, options etc etc...but kaafi khayal maangti hai car - aur petrol pe tou bht tareef krte hain log - i drive it n cng (kyu k fuel apni jaib se dalwana hota hai :P)- my sis kit is removed and is installed with normal one. so, since repaint thing is same in both the cars, you can go for it - but again, we do not have any idea of its actual condition, engine, documents etc.
Since you opting to deal with a 'jannay wala' so NEVER compromise on genuineness of documents, original number plates, engine & chasis numbers matched with original Suzuki Invoice, original tikli...these things can make any car a hell for a buyer, if compromised on.
Rest assured, Liana is a must buy for those who wish to have a 'Honda city' made by Suzuki
