Thats my question, just like the title says. If there were two 355 Spiders... model year 1998, same color combo, same condition (mint, perfect, no stories, clean ppi, recent service, clean title/carfax, less than 10k miles, no track use, etc., etc.), same, same, same. They were side by side for sale. However... 1 has a 6-speed and 1 has the F1 option. I'm not asking which one you prefer. I already know I prefer the 6-speed. If either, which car is more expensive? How much more?
