The Toyota Glanza is the first outcome of the tie-up between Toyota and Suzuki. Both the companies have actually collaborated with each other to and as a product they came with Glanza under the Toyota banner.
If your city does not have a Toyota service center and dealership, it would be hard for you to get after-sales support from the brand. However, we would suggest you to check out the other car which shares a lot to the Glanza in terms of performance and features. You may check out the Maruti Baleno as well which is a close competitor to the Toyota Glanza.
