It is not a Superleggera; like d4rk mentioned above, it is indeed 'just' a LP500 Gallardo with mods. It does however, still remain a Lamborghini ;)
The are several exterior differences between the first-gen Gallardo and Superleggera:
1. Stripes down the sides (on the LP570, the Superleggera wording is reflective)
2. CF side mirrors
3. CF rear spoiler
4. 15-spoke alloys
5. Aero tweaked rear diffuser and bumper
Quick point to note; the LP500 Gallardo and Superleggera have the same front bumper. In the new Gallardos (LP560 & LP570), the front bumper is completely different.
