Welcome to the forum D4B. In my book, the car has clearly been misrepresented, you were deceived by the salesman. Without a full LRSH, its value is diminished and might cause futurfe warranty claims. If you paid top dollar for a clear diamond you wouldn't expect it to have inclusions...... Looking at the "LR approved" site, all vehicles are checked and come with a full history.....
