Lack of integrity. Watch out on cash deals

We bought a car from E motion cars, the salesman was great and everything was wonderful. We told him that we would be purchasing the car cash, we were then told that that car was already sold, but they have the exact same one on the floor, we test drove it and decided to take it. Now 1 and a half years later when we want to sell it, we were informed that it was in an accident, now it makes sense as to why when they heard cash deal, they decided to sell us the one car instead of the other. No integrity.
