Don't think you'll get close to that. I am seeing talk of 10K overs but that is for cars that aren't delivered yet. Don't forget that all the 918 owners had first refusal on GT4 and GT3 RS and I know of a few 918 owners who are taking one or both and I think there are circa 70 918's in the UK. I would not expect them to take them for long however and they will turn up on the 2nd hand market fairly soon or be spun back to the OPC list. There is also noise about an RS version and a Gen 2 with PDK so soon as those start to become clearer early next year people will order and bail from the GT4's they have. Porsche are also building more than planned I believe, so suspect this will dilute the current overs and when rates start to rise as they will shortly the overs market will align I feel.
