Actually, it’ll take more than a kidney to get your grubby little paws on this sub-18,000-mile 1973 Datsun 510, because it’s not even for sale. Despite many inquiries, it’s stayed in the same family for 40 years and three generations. Think of this post as more of an inspirational tale, one that offers hope to those trying to find an unmolested example of the quintessential Japanese sport sedan before the rat rodders and engine swappers have their way with it. See, Virginia, mint 510s do exist (as long as you don’t mind a slushbox)! Even if the owner insists on hanging on to this heirloom, isn’t it nice to know that it’s out there?
