Its located in outskirts of panvel, near palaspha phata, just before entering the Mumbai-Pune Expressway on the right side of the road just behind Appa Cars. If youve got your vehicle in accident around that area, its always beneficial to go to a authorized service centre/ repair centre. Being a surveyor I have closely worked with the staff present at the workshop. As a customer you have to deal mainly with the Bodyshop/ Service Advisors. There are around 4 advisors and all of them are humble and helpful. They also ensure that the work is done on timely and neatly basis.
Talking about the workshop, its highly maintained and equipped with high-end equipments and one need not worry about the type of repairs as the Toyota follows a strict "operation procedures" and Wasan, Panvel workers follow them.
So feel free to drop by the workshop either for service oe repair paint jobs and you will feel happy.
Also, I would like to add a point from my live experience. One day I was sitting at the workshop conducting my official work, a customer walked by asked for replacement of front windshield of the glass. As the part was available with the workshop, they got it replaced within an hour and delivered the vehicle.
