Dodged a double bullet there my friend .
Porsche buyers are horrible people , self entitled idiots thinking they are something they aren't is my description .
I've sold a few Porsches in my time and they nearly always attract the swarms of fools .
He was trying to make his own set of rules , overruling you and your selling methods , soon as they try that with me , they get corrected or I stop the sale .
Always another bum for the seat , less trouble and less hassle for you .
He would have had checked again , sending you bills for future proofing the car . warranty claims would run into 4 figures too as that's what Porker Buyer do ,
Best deal you made was not dealing with that fool
