Don't be afraid of change! Often it is a good thing. Mind you I have been going to the same barber for 41 years. I also have driven a four hour round trip for the last four years to get to my mechanic for the 968's! Does your barber have a son in the biz. Mine does and that's my replacement strategy! Don't have one as yet for the 968's but working on it.
With these cars being over 20 years old and only about 4600 or so sold in the US, I realize how lucky, and I mean lucky, I was to find and replace my transmission and engine within days of starting my search.
These cars will only get more difficult to service parts wise as time goes on. Thinking of breaking the old engine down for it's parts and just holding them.
So finding and retaining good and knowledgeable 968 mechanics will continue to be a chore. God luck William. Don't sell yet!
