Reneging on sale of car
I recently moved overseas, and
advertised my car in Somerville, MA
for sale on a website. A trusted friend
handled the inspection. By email I
agreed to sell the car to a CT lawyer
for $8800. He emailed me a bill of
sale, and I signed it and sent him a
pdf of it, Fedexing the original to my
friend who was going to attend the
handover of title, which I signed but
did not fill in. My trusted friend in
Somerville was to put the buyer’s
name on the Title at a handover
meeting. The buyer even emailed me
a bank check with my name on it for
the $8800 agreed price. The buyer
has not yet picked up the car.
Meanwhile, while this is being
organized, I suddenly got a
trustworthy, much greater, offer for
the car. I emailed the CT lawyer and
explained, and said I wanted to
accept the higher offer if he can’t
match it. I offered him $100 as a
courtesy.
He said no, that he believes that the
transaction makes the car his at
$8800, and he wants to pick it up
and get the Title.

What do you think? Am I forced to
give the car over to the lawyer, or
can I legally renege because I have
the title and he does not have the
original signed Bill of Sale?

Thank you.
