Murphy was part of an antipodean contingent that travelled to the UK for the Super Touring Power event at Brands Hatch last weekend.
While he was there in a competitive sense, racing a Nissan Primera Super Touring car, he was also reacquainted with his former Tasman Motorsport VE Commodore Supercar (above), which is now owned by Alex Sidwell and lives in the UK.
Murphy cut demonstration laps of the iconic circuit in the big V8, the reaction to which left him wanting Supercars to bring its full field of modern cars to the UK.
OPINION: Why Super Touring Power should become a regular highlight
"It was awesome. Straight away it was like, if you're going to take Supercars somewhere, this is where you take them," the four-time Bathurst champion told Autosport.
"I mean, can you imagine the crowd here? You'd have as big a crowd as you'd have anywhere in the world if you brought the cars here.
"On the GP circuit, it would be some of the best motorsport you had ever seen. In a Supercar you can hit kerbs, they are so good over the small kerbs. They would just be spectacular.
"I never even got close to experimenting or seeing what the potential [through Paddock Hill Bend] was. The session was just way too short, unfortunately. But the speed a modern Supercar would go through there would just be spectacular on the limit."
