HAHA, How many top of the line sports cars are white? Well if you must know Porsche, Lamborghini and BMW. OK, I don't know if you have noticed but most BMW race cars are white. Does the LM come to mind (Oh wait, I am sure you don't know what the LM is), what about the E36 Racecars? The 1999 Nurburgring Taxi was a white E39 M5. Are you forgetting about the white Lamborghini Diablos. The Porsche GT3 is available exclusively in red, silver, yellow and white. There may be other colors but I am sure of those. And if you must insult the interior choice, what about Alpina? Very likely the most well respected BMW tuner. They have an interior leather package called Ivory. You may view it through the link below. So, to answer your question. YES, there are many top of the line sports cars available in white. Color is purely objective.
