I'm planning on keeping them Peter. I'll likely only sell one if a suitable 246GTS comes along as a replacement. I really enjoyed the whole process of restoring the first one and learning all about the model. I've still got a few bits to do to that car including having the correct heat stitched vinyl interior put back in the interior. I'm having that made in Italy just now by Luppi who do all of the interior restorations for the factory's Classiche service. Longer term they should be a fairly safe investment. It's a bit like an international treasure hunt with these cars as I've sourced door marker lights in Australia, a jack with vinyl pouch along with an owners book pack parts manual in Florida, an owners manual from New Jersey, numerous items from Ohio, a hazard warning triangle from Cambridge, dash mousehair from Holland, interior retrim in Modena, some vehicle history documentation via the Maranello archive etc.
I've been bitten by the "modern classic" bug and also have a 1973 911 targa I bought last November which will go into restoration this coming September.
