OK, for a short while I've hidden in the shadows of this forum... Being my first post, here's an introduction:
I grew up with Porsche autos, and I have always had a passion for them. This probably isn't the best post for a first one here, but I don't care...
First off: everyone here is a Porsche lover! Of course you appreciate your baby, but the fact that many people drive the same car may motivate you to seek exclusivity.
As far as modifying the looks of your car... it's PERFECTLY fine, no matter what anyone says (we're not children here, I hope). Here's the deal... if you prefer your Porsche stock, keep it that way.. if you think that all body kits and spoilers and whatnot are hideous, then woo hoo! You've suddenly got less competition in terms of aesthetics on the road every time someone changes the factory look.
Now, if you want a little more than stock, in order to obtain a distinguished measure of uniquity, you are not the first, nor the last, and you are correct in pursuing what you want from YOUR machine (a magical machine, but a machine nonetheless). Some of the more seasoned Porschephiles are familiar with the "Special Wishes Program", from which many unique autos have emerged. If you buy quality parts and install them properly, I do not see a difference between what you are doing at your local (quality) body shop, and what Porsche engineers have done for a LONG time.
To end this excessively long post, I'd like to just say... Porschephiles need to stick together! We're a privileged bunch, guys.
