Bangers and Cash - Season 4

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.

Two iconic British classics find their way to the Mathewsons' auction room; Dave heads to North Manchester to pick up an Austin A30 and a Morris 8 E that's had an alternative paint job.

An impressive collection of five iconic cars arrives at Thornton le Dale, including a 1967 Crayford Corsair and a 1966 Ford Zodiac which emerge from a garage in Selby.

Nothing screams 1970s more than a Mk3 Ford Cortina 2000E. Derek Mathewson heads to Brigg to value a 1974 example with classic Coke bottle styling and a sweet Pinto engine.

Dave goes to Wales to bag a Sierra Cosworth, a sought-after car in the bidding market. Dad Derek gets his hands on a more sedate 1926 Standard Tourer - a quirky little motor.

Derek heads to Suffolk to collect two Bentleys with a majestic pedigree; Cynthia a stunning 1963 S3 and Harry, a 1965 Continental.

Dave heads to West Yorkshire to collect a rare 1926 Dodge bus. Derek gets his hands on a rare Vauxhall Victor VX4/90 police car that is expected to sell for more than a few coppers.

Dave heads to Bolton to pick up a classic Italian sports car - a Lancia Fulvia 1.3 Sport styled by Milan coachbuilder Zagato.
