To me, it's a no brainer.
If you have an old car, or you travel far from home (cross-countrying) a
lot, it is way worth the investment.
I took the Plus card (gold?). It gives you in Quebec a 100 miles towing
limit.
If you had a brand new car, you may not need it (similar service might
be included in the warranty), but with an old car... so with a vanagon,
it is compulsory.
