I have bought an Alto car in 2011 I used to take a visit there after every three months for servicing.
They took more than 10 days for a normal service and a quality check takes atleast 15 days.
However service is very nice.
They service our vehicles quite nicely.
Maintainance charges are quite high.
After 2013 I havent took my car there im taking it to peaks auto pvt limited for any service I feed the need of.
