From 2013 until 2013
The US-only Lime Rock Park Edition was produced in a limited run of 200 cars near the end of production for E9X cars.
The "Lime Rock Edition" was a $ 10,000 option over a standard M3 as noted on the window sticker. This included the Fire Orange II paint which all cars were painted in since it was the only option.
Over the years the LRP M3s have quite understandably become a collectors car which only led to an increase in value.
