Auction Direct Auto Sales

This is total shady business. The person I dealt with is Fernando Rocha via CL when I posted my Lotus for sale. He contacted was interested and so excited to buy it. He came to take a look and we agreed on a price to purchase at $ 28K. He said he had cash ready in hand w him in his car to pay me and lets’ do the transaction right there. This caught be by surprise and I thought something was up. I agreed to the amount and he stated he would come the next day to make the deal.
The next 2 days he wouldn’t return my calls as others were interested in the car. Finally he got in touch w me and said he can do $ 26K and started stating things were wrong with car. I agreed to $ 27K and he went with it. He wanted an agreement return stating there are no issues w the car and if there are major issues I would be happy to fix it, ie like the car looks like it’s leaking oil so if it is let’s get it checked out and if it’s fixing I would pay for it.
The agreement is that he would come the next day to buy the car, but then he requested to goto him in Concord. My GF and I went all way to Concord to do the deal. After the deal was done, he started asking for agreements for 1 year for the car if something went wrong etc. This was so confusing as he agreed to 1 thing and then wanted a crazy 1 year agreement if something went wrong. MY GF at the time tried to tell him this is wrong and it should be a standard clause, and he got upset with her and asking her this isnt her business, etc.
Every time I emailed he would not respond and call me. Also when I asked to do the agreement via email he wouldn’t respond to me and say type it up and bring it to him.
This guy is a clear scammer probably does with other CL auto sellers. He tells them the car is for them and really his buying and reselling them at his dealership. Also trying to get the auto sellers to pay for any items he doesn’t want to pay for on his end after purchasing the car.
Be careful I think he uses several different names and business names to do this. My gut was right this guy is a shade ball trying to rip people off. He goes by the name Fernando, but I’m sure he has alias. His a bit out of shape, around 5′ 9″, Brazilian, and has a slight accent.
