Guys, I made a mistake and need some sincere advice. I am currently having 2004 wagon-R and upgrading to Tjet. I did not want two vehicles and I went to evaluate the car at true value. I was happy with the evaluation price and agreed to sell it off. I signed some document there, I don't know what, and handed over the originals. Since I did not have Tjet delivered at that time, I asked the true value guy to let me keep the vehicle for a couple of weeks, to which he agreed. So the car is currently with me now. But some sudden turn of events have necessitated me to continue with Wagon-R for some more time as my parents are joining me for a long time. Is it possible to get the deal cancelled? Or would they have changed the ownership already? Please guide me as to what options do I have now to get the papers back. I am ready to part with some money to keep the car if required, but how much would be a justified amount?
