Do people know when car dealerships have hugh discount sales it can be a ripoff?

the first thing to do is one drive,look at the car and get a friend or someone who know a lot about cars to shop with you because car salesmen are liars. second look at all paper work before signing ask questions keep asking till they run out of answers as soon that happen time to leave and don't let them make a extra deal so you can't leave. third always do your homework on the car you like and look to see if the price is fair to you since the payments will be good and fair.
