i am also having 2006 alto ff cng, uptill now driven about 70,000 km total company maintained by suzuki 3s dealers , all orginal except both bumpers which re-painted 2 years back, compare to mehran yes its comfortable, better breaks, better suspensions , better seats, soft gear shift, with ac engine dont heat up
BUT
car pickup far less than mehran, specialy its hard to over take with ac and some times i have to turn off ac at time of rapid acceleration, starting problem ( since new having starting problem i.e if first self miss than cant get started on cng and must have to convert on petrol for starting so i always try best to start on first self have showed car to differnt suzuki dealers but problem still there.
millage in city with ac 130 km
on highway with ac with speed 120 km = 110 km
highway with ac speed 80 km = 180 km
highway without ac speed 80 km = 200 km
top speed with petrol 140km ( but drink a lot petrol )
top speed on cng with ac 120 km
