One car that is a keeper, however, is the 1930 Sunbeam 16.9, a part-exchange from his retail days.
Derek has fallen in love with this tourer, and keeps it in good ‘oily rag’ condition.
Unlike the Singer, the Sunbeam is a car all the family loves, its 2.1-litre straight-six and open body endearing it to those otherwise immune to the charms of pre-war motoring.
“They really are powerful,” says Derek. “They romp up hills. I just need to fabricate a rack for the back so I can put a luggage box on it.”

The collection isn’t just for fair-weather use, however: the 1958 MG Magnette ZB Varitone was Derek’s regular transport last winter, the latest in a line of ‘winter cars’.
“I pick something I think can stand up to the weather and I Waxoyl them,” he explains.
The Magnette is fitted with an MGB engine, and he is now looking to fit an MGB rear axle to make a better cruiser out of the car, but he otherwise loves how it drives.
Derek Mathewson has an appreciation for pre-war vehicles, too
In sunnier times, Derek’s daily driver is either a mint 1961 Morris 6cwt pick-up or a 1965 Bentley S3 Continental: “The Bentley was very much a car that found me – as part of a pair, actually.
“The vendor didn’t really want to give them up, this Continental and a Standard Steel S3.
“He was especially upset about the idea that they were going to be split up, because they’d been a pair in his ownership for about four decades.
“Unfortunately, I just had to tell him: ‘Whoever buys them, buys them; there’s nothing I can do about it.’”
“The best cars are the ones you find by accident. They almost find you”
A couple of hours of driving back to Thornton-le-Dale with the two cars on a low-loader, staring at him in the van’s rear-view mirror, changed Derek’s mind, however, and he bought both cars from the vendor, promising to keep them together for at least a few years longer.
“I wasn’t looking for one,” he admits. “I don’t think you really know what you want until you have it in front of you.
“I used to think it was quite odd when people would come into our showroom and not know what era or type of car they were interested in, but I can relate to that more now.”
Mathewsons is the subject of the popular television show Bangers & Cash
That makes four Bentleys in the Mathewson collection, because he also owns two MkVIs and reckons the model is the most usable luxury classic of the 1950s, with performance that still does well in modern traffic.
A fond memory of actor James Robertson Justice driving them in period helps, too.
The silver 4¼-litre is used most weeks, but a black 4½-litre is waiting in the wings to replace it once it’s back on the road.

Derek won’t be drawn into saying if there are any classics he’s still lusting after, reflecting the content figure he cuts throughout our conversation.
“A lot of people can’t live without this or that, but we have so many cars coming through here, and I get my fix from many different things,” he says.
“I know I’m very lucky. I’m living my dream and what I know is a dream for many people.”
