I went to Suzuki Motors, one that is located on Korangi road to ask about the new models of Suzuki. He just didn't knew or wass just pretending that we are not going to bring a new model in 2006.(He was looking like a illiterate one with a suit)
Well if you run Alto with a CNG oil its pickup is really good. But with the same petrol oil it sucks, really, believe me.
My vote is for Alto as it makes less noise as compared to Cultus as well and also the back seats are really more comfortable than Cultus
