I faced the same situation earlier this year as I needed to collect a ww2 truck of under 3 tons. I hired a 7.5 ton beavertail truck, drove down to the Channel tunnel, onto the freight Shuttle and drove up through Antwerp to Holland. I loaded the truck after a night in a cheap hotel (weekend rate). I loaded up bright and early on the Sunday morning, parted with my hard earned pennies and returned home. At the exit of the Channel tunnel I was waved straight through by HM Customs and on home. £360.00 of diesel burnt and £180 for each crossing on the Shuttle was not cheap, but I'm a control freak and I knew what I'd purchased before committing my money, had ensured the seller had cancelled the Dutch registration and declared the vehicle as exported. Much later I registered the vehicle on British plates and was able to hand over the old Dutch papers (which were checked by the local dvla office). The only hiccup with dvla was I didn't have any Customs import papers, which the local dvla helpfully produced for me to sign and all went through after a few days. I hasten to add I had previously had the vehicle's age inspected and verified by MVT as well. The dvla were helpful and exact in there requirements. It was a long drive 9 hours out and the same home but well worth it. Good luck. Jerry
