He and I are with you 100%, and it is that route he is now going. A Porsche stamp and courtesy car would have been nice, but not for £2K more than what he can get from an Indie.
It is quite fun trying to justify OPC prices though. Even at £200/hr they are either very slow on some jobs, or mark up parts spectacularly, or expect it to go wrong and take a long time, or all of the above.
I appreciate, if they are going to replace all the bolts, the price is going to grow. Years ago I replaced the bolts on the exhaust system of my 951; £100+ for bolts and gaskets even back then.
