If I was fortunate enough to have $375,000 to spend on a car I'm not sure I personally would go with an LFA. It is a great car no doubt. I love the design and engineering behind it. However in the end I think I would spend $135,000 on a Porsche GT3 RS and then spend $80-90k on a new 2011 F10 M5 for a daily driver. That would still leave $150k to spend either on the two cars or on hookers and blow.
Edit: Or just spend the difference and get the GT2 RS instead.
