I think if you really like a car and you can afford it, just do it. Porsche's car are very reliable relatively speaking, as long as you keep it well maintained on time with an experienced workshop that deal with Porsche's car, you will enjoy the ownership thoroughly.

I can totally understand the "excessive" feeling of buying a luxury brand like Porsche though, it can be intimidating somehow if this is your first time, but if you really do like it, go for it!

Offtopic: Any Porsche community/club/forum around here that I can join?
