Few points:
Yes RJC is a distributor of ours just like some of his products can be purchased from us....almost all of us Buick vendors sell to each other. As for starting a Turbo Regal yes it will do it. I have done cars in a junk yard that have been completely dead and it cranks them over.
It is amazing that something that weighs 9 ounces can jump a car. Its great to use to charge phones etc and has a powerful flash lite.

Shop local to me has used it to jump a high compression 1968 Corvette.
