Are some of the later T25's still Aircooled?
There not the same as a T2 but for the money T2's are fetching (a shell currently on Ebay with NO engine is BUY IT NOW for £750) so maybe a T25 might be the future.
As for me i'm still awaiting news on whether or not the wifes nephew is going to let me have his old knackered T2 for FREE, if not then i might look at a T25
