I have checked into almost e-v-e-r-y tpt firm from the USA into Canada, and I suggest contacting Hansen Global.
Joanne was outstanding, and she was 20% below Advantage TPT, Dependable Auto Shippers, Fedex...(tell her "6 ft 2" sent you...code for discount)...
From my discussions, I sense it is easier to allow a firm like Hansen to truck it through USA customs. As long as your Speedster's VIN # indicates it is >15 years, it is classified as an antique, and bypasses all the inbound issues.
I am paying $1821.CAD to tpt from Larry's garage in Greenville, SC to the 'Sufferance Warehouse' in Burnaby B.C., where I can choose to have a broker deal with the final clearing process for an extra $200-400.00 (negotiable), and from what I have heard, it is worth the extra money.
With border security being sensitive these days, the border dudes like dealing with their own...so it is worth it.
