I don't really see these as genuine rivals. The GS is a daily drive and very practical, while the 430 is an out and out sports car. There's no doubt that a Gallardo, a 360 and a 430 are all quicker than a GS, but if you are only going to drive to Waitrose, who cares? If you are spending, say, £80k, you'll go the Lambo/Fezza route and rightly so, but if your budget is £25k be thankful that you can afford a car which is not that far off the pace. It's a lot of car for the money.
Stick a Tubi exhaust on a Ferrari (as I did on my 360) and the high-pitched wail can't file to excite. Lambos, on the other hand, are loud without "singing". And the sound of the Porsche doesn't come close to either.
Over the last 15 years I've run several Ferraris, Lambos, Porsches and Maseratis as my daily cars (along with the compulsory Range Rover) but at 45 I'm now too old to drive a Lambo, so my realistic choice is now down to the the 3.
Talking of which, I'm in the throws of buying a 612. My daily car needs to be able to do the school run, so I view this as a good compromise between fun and function. A bit like the GS.
