Buying secondhand skoda superb 1.8 TSI AT

I purchased second hand October 2010 model Skoda Superb 1.8 TSI AT car from Mr. Anil Shamjibhai Patel of Surat. On very third day after running for just 150 km including 100 km for bringing car from Surat to Valsad the car stopped with display that the "Gear Box is over heated". The car could not move at all. So I call the Skoda Authorized dear - Torque Automotive, Surat and I was informed that the failure is due to Mechatronics. I was told that changing the same will cost Rs. 1.90 lakh. When I inquired about the guarantee, surprisingly I was informed that the kilometre is tempered so Skoda company can't give any guarantee on new parts replacement. It is difficult to know whether the kilometers are tempered in very good looking second hand cars. Now my car is in the Skoda workshop - I am worried whether to make payment of 1.90 lakh and get it repaired for which I have paid premium price for the good condition or forget the car because I don't know whether it will run smoothly later. I request all buyers of second hand cars to get the car checked by authorized workshop before buying such premium cars to save yourself from getting cheated and in the condition in which I am today. Because tempering with kilometer is actually a crime, but I have paid money so now nothing could be done.Good exterior & styleWorst mechatronics
