Hello Pedrof!
Welcome to the wonderful world of Boxster! Congrats on your very fresh unit!
I'm afraid that even with shipping, pelican parts is still cheaper than sources in Singapore. Some have mentioned HK as a possible source of cheaper parts but I have yet to find an online source based in HK.
PS: I also debated about getting a brand new Subaru BRZ / Toyota 86 and a pre-loved Boxster. I think it's a good car and I would absolutely love owning one...if I were back in college! Besides, in a few years, it would just be another rice boy racer.
