Many who come to see the local sights do it from the seats of four different Porsches in one day.

The business, started by Gavin Little earlier this year, has also helped other local tourist operators such as Cliffhanger Cafe.

Mr Little was keen to share his cars with people on some of the most scenic and most sensational roads in NSW. He discovered how great they were from the seat of a 1977 Carrera 3.0 over the past decade.

He is a Porsche enthusiast, but his hunch that others would be as well is proving correct as the warmer spring weather helps the new business grow.

His tours start from the business park at Helensburgh and wend their way south to Bald Hill and then over Sea Cliff Bridge.

"Ducking through 100-year-old mining villages, we head south to a stretch of road that is equal to anything I've ever driven in Europe," Mr Little said.

The drives involve drivers regularly swapping cars, taking in Macquarie Pass with mainly second and third gear turns.

"I could easily do this job forever," Mr Little said.

His fleet includes an early model Boxster and a 911 993 Variocam.

"Our philosophy is not to have 'executive express' type experiences - we'd rather have people working for their revs and pace, and then hopping out of the car with a big smile and feeling a bit, but not too, shaky."

Drives include lunch at the Burrawang General Store Cafe before coming back down Jamberoo Valley Road to Saddleback Mountain and then up to Bulli Tops for a quick coffee before returning to base.
