Overview: A 1970 Excalibur Roadstar, once owned by Roy Orbison, arrives at Thornton le Dale. Styled on the classic Mercedes SSK, it's a repli-car with a huge pedigree and even bigger 5.7 litre V8. Dexter the dog, a pedigree in his own right, needs a bigger sidecar and a 900cc Triumph Thunderbird with a matching top of the range custom built wide-bodied sidecar fits the bill. And Derek heads to County Durham to collect a 1935 Austin 7 Ulster that's been completely rebuilt.
