...All that for 750$ MSRP.
Your thoughts on if it was worthwhile.
Well here in the US, you can count on about $130-$200 for each of the four(4) scheduled services with the first one free anyway. So if your local dealer is on the low side cuz of demographics, big-cityness or busyness, etc. AND you paid full MSRP, you might find it not such a good deal. On the other hand, if you live in NYC or somewhere that the cost is higher, and increases faster each year, and you paid less than MSRP, you might be well ahead. It's really just a matter of simple math, and NPV - all of which you can figure quite closely if you have all the facts relative to YOUR case, car and prices...
Btw, the same goes for Audi's extended warranty coverage - just do the math. You can find statistics on after-warranty costs per model, against what YOU have to pay, how many miles YOU'LL drive, etc. This is not hard, but most folks just don't think through it, instead letting themselves get talked into or out of a good or bad deal.
Remember this though - ALL of these plans and prices have Audi's actuaries all over them, and they're in this to MAKE MONEY, so if peace of mind is YOUR main driver at even a fair price - you might be okay with it. Otherwise, you're likely to fair better on your own almost always regardless...
