Do they have the same engines or different ones?? PakSuzuki introduced an electronically fuel injected (EFI) 4 cylinder engine towards the end of 2007. Whereas since its release in 2000, the cultus has had the carburetor 3 cyl engine up to mid 2007. So verify which car has which engine.Make sure to get your car checked by a mechanic before purchasing, buy whichever one has the engine in better condition.
On a sidenote, ask both owners what oil they're using, if either one say 20w50, stay away from that car. Cultuses. no matter the engine will use 5w30 engine oil. If you can get both cars on a test drive and compression tested too.
