Adam Harling, from Great Britan, sent me a picture of his own Punto GT and a quite long list of modifications:

• Pipercross Panel Filter
• Modified Airbox
• Hand-Made 2.5" Single Silencer Exhaust with De-Cat Pipe
• Gmax Springs (lowered by 60mm)
• 15" Wheels with 195/45 tyres
• RedDot 6groove Front Disks
• EBC Green Stuff Pads
• BFGoodrich Braided Steel Brake Lines
• DOT5 Brake Fluid

Here there is a picture of Adam's Punto:
