the guy has an alto with his own installed 660cc used engine and transmission. going with family of 4 and luggage upto murree or beyond. do not compare this car with any other 660cc. a used engine and transmission will give up any time under heavy load. what will he do with his family stranded on the highway. curse the guy who said kuch nhi hota! dont compare this car to latest (or 5 year old) japanese imports they are much more powerful. kei cars are not meant to be hauling 300 kgs up mountains.
