The Porsche 718 Cayman GT4 RS models are finally starting to roll out and people can not get enough of them. Well, those who can afford them. Just to refresh, these had a starting price of just a tag over $150,000 and the sky is basically the limit in terms of options. Naturally, the Weissach Package adds a quick $13,250 and several other things you wouldn’t think would cost a bunch of money, but actually does. Then of course is the markup. On the secondary market, sure, you can expect that. However, a Porsche dealer retailing the car as new with just 18 miles? Wait until you see this asking price.
