I owned Spark as I found this is my car looking at cute little car. Well everything goes well with except for mileage. Service after sales by Orange is perhaps the most poor services available in India. Even a sadakchap mechanic will give you a better service than that of Orange.
You will by harassed by all means for delay and as well plundering your pocket. GM Motors have tall claims of three year free warranty, service labour & what not. Its only for publicity.
BEWARE GM! BEWARE ORANGE!
