It is a very common malpractice being adopted by Suzuki dealerships now-a-days.
I wanted to book Alto VXL AGS, and since Suzuki gave very very limited quota of VXL, the dealership, which agreed to book the VXL, forced me to install a useless tracker, costing Rs.20K from them.
Since, I was in dire need of a cheap zero meter auto car, so swallowed that bitter pill of 20K 
Sab ganda hai par dhanda hai...!!!
