I know that very few people go for reviews whens something good happens.
I was bitten by bad service by Sanjay Hyundai in Pune. When I moved to Mumbai it was completed different. The service by Sharayu(Turbhe, Vashi) was excellent. The staff was nice, service was good, when I was unhappy about cleaning once, they did it all over.
The car was always ready at the time promised.
Excellent service. Don’t know about the sales part though.
