That doesn't tell us what's out there - only that you only looked at cars on coilies!!I didn't look at a single car that wasn't on Coilovers.
Of the 9 on PH today (all under £12K plus one at £23K ) 1 is on DRC, 2 on coilies, and 6 don't specify, one of which claims "Audi upgraded suspension" (who knows what that means!!)
Given that PH is basically where enthusiasts are selling their cars, and given that the contention is that being off DRC is a selling point, I would be surprised if all 6 which don't specify are all on coilies.
My guess is that it may now be up to 67% on coilies as most of these cars are now in the hands of "enthusiasts" rather than folks who owned them from new(ish) with a view on value preservation etc.
