cultus is a very bad car, its still the old chassis dat came in 1992 i think, same susupension, a 3 cylinder engine. bad suzuki quality control as usual, i speak from experience.
If i had to buy, i would go for a Santro. ATleast its newer, has a efi engine, very good fuel consumption. Put in alloys in a club 'n do a bit more to it, 'n it really turns out good.
