Dave as far as the title goes.
I haven't registered one recently here in CA.
cars go out of the system after 7 years.
and I don't know if anything has changed but,
the last 2 we registered all we had to do was
show a bill of sale saying that the cars were
on the sellers property for like 30-40 years
and have not been on any CA streets.

they will get the paper work going and you will need to
get the VIN verified
by DMV
or AAA(if you have it)
or a law enforcement officer.

and because they are trucks they will need to go and get
a weight slip,
to get the paper work finished.

I hope nothing has changed I have like 6-7 cars(trucks) to get titled
.

I would check with DMV where you live
it might be easier than you think. Ron...
