You are saying if you was to, I hopefully read that as it has not happened ?

When you buy or trade privately that means AS IS,,, there is no recourse. I strongly advice any purchase from dealer or private is subject to an independent mechanical inspection prior to purchase, it will cost a few bucks, but you will have peace of mind,,, if an inspection cannot be arranged I would walk away from the deal.

It had hsppened.. So theres no way to get the vehicle back at all?

No, from what you posted it's a done deal,,, we all learn from our mistakes and I somehow know you will not get burned twice.
