Most terrible test drive of the Thar

I was sent a red hardtop petrol 4x4 variant from the NBS showroom chowpatty Mumbai. Immediately as I sat in the car the engine heating warning came. The full test drive the car barely moved 13 km/h at full acceleration. How could such a car be sent for a test drive. More importantly the car had driven only 18,000 kms, which says all about the quality of the engine and this vehicle. The car is over priced and besides exterior looks, it was extremely disappointing, especially since I owned a Scorpio and was very happy for 8 long years.
