Yes, the seats should be relatively easy to sell/swap with you netting a few grand in the process.

BTW... I love the Arena Red 993, there was a friend of my parents that had one when I was about 17, I loved that car!

 

FWIW, I felt the same way about my car/seats. I bought it from out of state and actually assumed I'd swap the seats out once I get it.

Then the car showed up and I sat in them. They are the most comfortable seats I've ever sat in. Perfect driving position. They're a little more tricky to get out of, but not bad. you get the hang of it. I also assumed my wife would refuse to sit in them, but she actually loves them. We took a multiple-hour road trip in the car a couple weeks ago. They were great.

As others have said, you could easily sell those seats for 5-7k if you ended up not wanting them. You could then buy a pair of regular or sport seats for 2-3k and pocket the difference. The seats are incredibly desirable, especially since they're not making them anymore.

That launch car in the posted link is a great looking car. It appears to have an aftermarket exhaust on it and some nice looking aftermarket wheels. Don't let the seats deter you!
