I concur with James's comment regarding buying a Porsche from a club member. My brother has been looking to buy an SC or 3.2 for a month or so and looked at about 10 cars, mostly with me along for moral support and to get grubby looking for oil leaks and rust. He was not a club member but I kept him aware of cars for sale in the Porsche Post, and we found the quality of those cars to be much higher than cars advertised elsewhere, usually with a full history and in better body, mechanical and interior condition. The prices of the quality cars was generally £2 - £3K higher, but in my opinion well worth it.
He decided quite early on to buy a 3.2 rather than an SC and after driving a 915 gearbox car bought a privately advertised RHD '87 Sport fitted with the G50 gearbox for around £14K. He only picked it up just this week and is well pleased.
I am in East Sussex and would be please to help if you feel you need any advice.
