I suppose Lamborghini intends to fully capitalize on its brand worthiness by providing a more interactive avenue to market and sell products under its name. This is much like its Italian rivals, Ferrari, who however seem to have caught on this brand marketing trend very early on and now has its name plastered on everything from mugs, cellphones, t-shirts, laptops and most probably on some kitchen sink too.
Anyway, from Collezione Automobili Lamborghini, you can buy online a mug for 24Euro (not including shipping) or customize a 1963 vintage look sweatshirt with your name for 170Euro. There are also mouse pads, pillows, teddy bears, menswear, womenswear, children's wear, Lamboworld items as well as Super Trofeo branded apparel (Super Trofeo is the Lamborghini Gallardo specific championship).
For those that do not only want to buy the brand but something higher up the product line there is also the Lamborghini LP640 by Versace lineup. The LP640 moniker comes from the Lamborghini Murcielago LP640 model that ironically had been recently discontinued. There are LP640 keyrings, bags, wallets and a belt. The key ring alone costs 205Euro, which is actually pretty reasonable if you intend to use it to hold the key of your 170,000Euro Gallardo. It would be as useful if it held the ignition key to a slightly used and slightly battered Fiat Panda.
