Enclosed car shipping recommendations?

[jerry455]

Hello All,
I'm looking at a '71 Buick Skylark for sale on a Buick specific forum, nice car at a solid price but I would need to ship from NH to Northern CA. (3,100 miles) I got a quote from Reliable Carriers for $3,950 with Hagerty discount and another from Montway Auto Transport for $2,619 cash price for enclosed shipping. Any experience or advice on this task?
I know it's not going to be cheap, but its a good price on the car so I'm just looking to weigh all the pros/cons quickly.
I'm sure somebody on here has some valuable advice or recommendations?
Thanks in advance,
Jerry
