first of all ,congrats on purchase.it is a good car.This car is actually the good old "Daewoo Matiz" which died along with daewoo went bankrupt years ago.and General Motors bought Daewoo shares in Korea as some of you knows.so ,they re-badged the matiz as "spark".There is a newer version of spark coming soon in india IIRC.

Still Remember Matiz was one of the cutest car when launched somewhere almost a decade back.
it is a succesful model in India.costs around Rs3lakhs(Indian rupee) on road.the chevy in pakistan is simply asking too much.the air bag version of spark is for grab at around 3.7lakhs(indian rupees).also ,expect dealer discounts of 10K to 20K along with free goodies here.Two Engine options 1.1litre and 796cc Engines.
