போலோ worst mistake of my life

I have a 2012 1.2 mpi polo highline which has run only 48000 kms and has again developed engine issue. Its EPC light is on and its engine and body is rattling and shaking like crazy. Last time it happened it had run 32k kms. Had got all 3 ignition plugs, spark plugs and the entire set changes for 10k approx then. So, got it to volkswagen service station, the engineer said that he'll have to check if there's a compression issue. He asked me to submit my car for 3 days. If there's a compression issue, then we'll have to change the entire engine set which will cost me somewhere around 25-30k. And 3 days for checking the issue and what if engine has to be replaced? another 30 days! I mean people buy cars to park in garage or what? I used to think that if you get your vehicle serviced in time at authorised service stations, it wouldn't give any problem. Thats true for Maruti & Hyundai cars as per my experience but not with this metal junk Volkswagen polo. Imagine what kind of a car would develop engine problems after running merely 48k kms and timely serviced every single time at authorised service stations only? doubting if i had a bad luck that i got a lemon, i enquired several indian car websites and to my surprise found many similar cases with this product. Buying a volkswagen thinking of german engineering and safety proved to be a curse. Now i'm stuck with this lemon, can't even sell it off worrying what the person who buys it from me later discovers all this would think of me that i duped him/her. its as good as a scrap now. I have already prevented 4 of my friends from buying volkswagen products. So, i advice you gentlemen and ladies even to think a thousand times before buying a volkswagen...
