Speculating on vehicle transport rates more than a week or so in the future is much like predicting what the price of gold or oil will be, as transport industry prices are market-driven, based on supply and demand.
We can tell you what it would cost to transport your vehicle this week, which will give you an estimate of shipping costs for the future.
We are happy to re-quote closer to your shipping date. Unless during severe market changes (i.e. major weather events, holidays or snowbird season), most re-quotes fall within about 5-10% of the original quote, so not to worry.
