The first thing we did was contact DMV for the "rules" to make sure we followed protocol. Then we got the forms we needed.
We placed an ad on Craigslist. We were selling my first convertible, candy red Mazda Miata in mint condition that was 7 yrs old and less than 10,000 miles on it. Yeah, I am very picky with my cars.
A man in KS contacted us and wanted it. After a lot of conversation and making sure he was who he was, etc, he flew to Dallas, hubby picked him up a tthe airport. The understanding was, we will meet at the bank. You can see the car, no haggling, then if interested, go inside the bank to finish the deal.
He took 1 look under the hood of the car, saw that it was impeccable, never drove it. Went inside the bank and gave us a cashier's check for the asking price. He knew he was basically getting a new car. He drove it home.
He has been in contact with us since via email and sent pictures of him and the car. He Loves it!
Be careful about who you deal with and be proactive on getting all info, paperwork needed.
