Haha, Swift has awesome brakes. A person I know has a GLi, he drove my car, braked really hard, ABS kicked in and told me that his car skids when braking. I then asked him " XLi to nahin hai?" he started laughing and told me it's a GLi. I then further proceeded to open up the engine bay and confirmed that it had ABS lol.
Swift's ABS brakes and Allah swt have saved me many times!
All the dealerships I've been to let me stay with the car. Yes, they do ask if I want to wait in the waiting room or a cup of tea- I just tell them, I love my car and I want to stay with it. Sometimes I help out by tightening all the nuts and bolts.
If you don't stay with your car- Expect something to get messed up. I've seen how they treat the customers cars, Revving cars, chilling inside and what not.
Been to 4 Suzuki Dealerships so far!
