Really big.
Getting anywhere takes ages.
Forget Public Transport.
Policeman give you big fines if you use a car and try to speed things up a bit..


You really must narrow down the field of your search, both in terms of cars and geography.
I would not buy from Florida, it's not a dry State.
You may get lucky as Floridians buy dry state cars and then sell them.....
I have done numerous trips to the States and I have rarely seen desirable cars, let alone on the road. It's not like the films. It's all Toyotas at the coasts and Pickups inland (Drewe will kill me for that...)
However, I have collected pre-purchased cars from the States and transported then to the docks. It was a very memorable "Road Trip". Ten inches of snow all the way across 3 States, there and back......
Be careful, buy wisely (and NOT just because you are there) and you will have a great time.
