In the late 1920s and early 30s his car raced 40 times in the world's first purpose-built motorsport venue Brooklands in Surrey, winning seven top races.
Mr Thompson said the car, which reached speeds of more than 120mph (193km/h) during its heyday, was "priceless".
The Yorkshireman, who has travelled across Europe and further abroad in his car, said he was enjoying his first adventure in New Zealand.
"It's very relaxing driving around here. [The landscape] reminds me of Norway and Scotland and the west coast of Canada," he said.
Thompson said he was an avid mountaineer and enjoyed the rugged landscape and mountains of the New Zealand countryside. "It's superb. The amazing thing is the mountains rise up so close to the plains, you're in and you're out of them so quickly. Everywhere, everything is so different, we had a very nice time at Mt Cook."
English couple Colin Pigott and his wife Ray Pigott were also in Masterton yesterday.
They drove a 1930 Bentley 41/2 litre VDP Tourer model, which competed in the 24 Hours of Le Mans endurance race.
Mr and Mrs Pigott were one of the 12 couples who spent two months driving through South Africa late last year.
And when asked about New Zealand, Mr Pigott replied: "What a fantastic country." The cars now head to Napier for Geon Art Deco weekend
