Value of Slant Six Car

When the supply of slant 6 cars reaches the status of "almost extinct", we will all be asking ourselves the same question, why did I sell it. (I'm getting a free one on Sunday, from a buddy of mine, for parts). Will probably look to Craigs List to get rid of it, after I get what I need. I am glad to see that there are some /6 enthusiasts out there to keep the "leaning tower of power" still viable. Howard
