Well it took only a few days but I reluctantly sold my nice 1923 Touring to a nice guy in Buffalo New Your. He is developing the river front and will have the car on display.. His driver called and says they have a closed trailer with ONLY a 6 foot three inch door height with ramps. By the car dimensions with the top down it should fit, but I have heard as the car tops the ramp you need more height. Will a 6' 3'' door opening work ? With the top down and folded of course
Yes that will work with the top down. The windshield should clear it by a couple of inches.
The highest point sitting flat (windshield)will be no taller going up a ramp and into a trailer (it will be shorter). IMHO, you're approaching this wrong. You don't know this guy or his trailer. You need to tell him how tall, how wide, how long and how heavy, and let him make his own decisions. You may tell him his trailer is ok, and he arrives with a utility trailer with a couple of 2x6 boards for ramps, no tie down points, nothing to tie it down with, or pulling it with a minivan. The door opening is just one thing to consider.
Assume worst case scenario - the car comes off the trailer & the top goes up.
On a multi car carrier -vehicles are off loaded,
stored outside in a yard, loaded back onto a trailer, several times ....
If it comes off - the top may go up ....
When it goes back in - the top may not come down.
You will be blamed by the Buyer for the damage .....
Unless the car is going direct from pick up to drop off with no transfer - no moving off the trailer it is loaded on - the shipping height should be calculated with the top up.
