Come on guys, we're talking NO financial limit!
Chassis: Chassis stripped and re-made from titanium.
Bodywork: Doors, bonnet, boot, bumpers, guards and etc removed and replaced by carbon kevlar items.
Engine & Gearbox: Transplanted out of a Ferrari 550 Maranello. Built by Koenig. Completely polished and detailed. Engine bay done in solid gold ala McLaren F1.
Interior: Alcantara... everywhere. Enough woodgrain to make a Bentley feel like a Bluebird.
Audio: The Alpine F1-Status collection. Twice over.
Wheels & Tyres: Carbon-metallic one-piece items. Bridgestone Formula One intermediate tyres.
Exhaust: Coming out the carbon-kevlar side skirts. Fully engineered to be legal. Titanium.
Every other piece you find on the car - replaced with something twice as light, four times as strong, and twenty times as expensive. Buy two Formula One cars to use as donors.
Now we're cooking.
