Amazing ...
I really wish PakWheels had such a setup in Islamabad as well. Islamabad has a very good number of fancy vehicles, but the owners are fleeced by couple of workshops.
I have seen several persons worried about the cost. To my mind, quality is what matters most. I pay around Rs. 2000 for routine maintenance at Toyota Islamabad Motors. Now, most people complain about high charges for routine maintenance i.e. oil and filter change etc. However, I feel happy when I see that they jack up the vehicle, tighten all the nuts and bolts underneath the car, check the doors, and look for any possible rattling sounds. Simple oil/ filter change is a 50-100 rupees job, but I feel happy that my car is taken care of properly. However, the downside with Toyota is that they dont believe in modifications, etc. and that's where the opportunity for a good workshop comes in.
I do hope you will expand your business to Islamabad as well.
Wish you all the best
