5. Vaydor
Price: $11,000
Vaydor is one of the modern looking kit cars for those who prefer this characteristic. Anyway, it stands among the easiest and cheapest kit cars to build, with the base kit being only $11,000, and needing just about two months to finish building it. What makes Vaydor having this relatively low price for the performance and the quality you get is that around 90% of parts needed to build it come from the donor Infiniti G35 (but only 203-2007 models).
