I can pretty much belive what you say Joe.
We had a fall out... Cough Cough on holiday with a BMW M3 (ok fine its not a Porsche but its close) and with all due respect the M3 had nothing on the GTi.
He came flying from behind and swerved in front of us narrowly missing us and then kept trying to pass the car in front who would not let him pass (Gotta love drivers like that)
When the M3 finally got the chance my dad (with a boot full of luggage, a teengager, a wife and 2 kiddies not to metnion himself floored the GTi and passed the M3. This peeved the BM driver off. How can a "golf" pass a M3? So he floored it and my dad floored it and up a mountain pass in a really nice left hand bend my dad kept flooring it. The Bm could hardly keep up and you could see he was trying.
Even through the bends where you would expect the Bmw to pass cos of better traction etc even then he could not pass.
I can safely say that on a straight or a drag the GTi does not stand a chance. But against most cars (even a Merc SLK) the Gti just has the advantage. For its size and weight etc its absolutely perfect.
Viva la GTi!
