I hear they are giving great trade in rates, but Step 1 of selling it privately is to not take personal checks and do as you did last time and both go to the bank.I hate the idea of trying to sell the Model S on my own but my guess is the trade-in will be 35% or even lower than what I could get selling it direct. But I hate the idea of showing people the car and trusting somebody is not giving me a bum check etc.
My oldest car I sold years ago for like $3,000 and even then they wanted me to lie on the form so they didn't have to pay as much tax. I hate people.
The last one was an original model year Honda S2000 with 7,000, mi on it that I sold for more than I bought it for but I lucked out some guy from San Francisco really wanted it and I met him at the Wells Fargo bank and watched him get a cashier's check.
