My son purchased a used car from a dealership about 4 days ago in which I accompanied him. The Buyer's Guide stated the vehicle would be sold As Is- No Warranty. Nothing else explaining any issues was written on that notice nor disclosed to us at anytime during the transaction. We signed the papers & took the car. Later my husband found the Buyers Guide under the seat & the dealer had written in ink that No Systems were covered and the vehicle was being sold as a "mechanic special in need of engine repairs." Customer has heard and is aware of noise coming from motor. Sold as is. "None of this info was provided to me beforehand nor did we sign anything stating we knew. Now there's engine problems and I'd like to know what are my rights/options. Please!
