A new Ferrari F150 2011 found under Decor / Misc. Decor, costs 0. You need Fast Lane or later pack for it to show in the game.
Ferrari F150 2011 (MediaFire)
NOTE : If you have TSRW then you may be able to make this Ferrari drivable. I originally made it as a vehicle clone of the EA Racing Formula. It allows the sim to go shopping / community lot but when the sim gets into it the whole Ferrari becomes invisible. When the sim gets to the destination and there is a parking bay the Ferrari again appears back to normal. If you do ( make it drivable ) please send me a link so I can upload it and make it available as a drivable vehicle.
