For me it wasn't a value proposition (in fact in Canada, there's no discount for ED), it's an experience proposition.
Of course, I'm not sure what it would cost to rent from the Welt, say, an M2C 6MT for 2.5 weeks and for 5000 miles, in answer to the idea that renting from the Welt would be better.
(I say 5000 miles because that's exactly what I drove in my
recent ED from last year).
