It may have worked in the Porsche club where there are very distinct models eg 911, 914, 924, 928, 93n, 944, 96n which are all distinct shapes. But with the exception of the SV, essentially all sevens are the same. All we're talking about are detail differences. The major differences in sevens are the axle, gearbox and engine types. Many people move between the variations on this eg people have gone from live to de dion, 4 to 6 speed, or xflow to Zetec, or even xflow to K.
Ah yes, but which HPC, the real ones (BDR engined) or the VX carb ones, or the Vx Injection ones?
Actually, it's better to get us all out together
In the forums we have the GOGs upstairs and the UTs downstairs, that's too much fragmentaton as it is, this is a small club, even more fragmentation would be silly.
