This Dallara model generation is very popular globally because of its modern design, full availability of Dallara new parts, abundance of privately-owned used parts, range of compatible technical partner's products, and performance per price point.
This car sold brand new for $92,000 USD just for the rolling chassis back in its day, and today complete cars are selling for around $30,000 USD. We've even recently seen a few of these cars go for as low as $26,000 which is an incredible price for a racecar of this quality.
