Once we get offers from VW, we will get two years to decide between buy-back and fix. Trade-in value would be maintained at 09/2015 level. However, if they can't fix them, what's the point on waiting? Buy-back values are published on VW's American settlement website, in ranges, until more detailed numbers are made available on July 26th. Canucks will only know what happens on July 29th.
Read a good point in this thread - if buy-back is treated as trade-in, that'll be a huge difference in sales tax.
With your buy-back, 1000$ credit cards from VW plus the compensation money, I say go for a new Sportswagen!
