6. GTA Spano
Sixth on the list and next in line we have a Spanish supercar built in Valencia by the company GTA Motor.
Even though the car started as a secret project in 2005, it was first released to the public in 2008 when the model was presented under the name of GTA Concept.
And in order to maintain its exclusivity, the GTA Spano will be built in only 99 models.
Set to be featured at the 2013 Geneva Motor Show, the latest version of the car has a 900 bhp engine which has been electronically limited.
Equipped with a 8.3 litre V10 engine, the GTA Spano can accelerate from 0 to 100 km/h in just 2.9 seconds, and can reach a top speed of 350 km/h ( 217 mph).
