3300 for 2 years...yes, that is steep. But I'd be inclined to do it...I assumne you have no history with the car, no chance to look for leaks, weeping seals, minir issues here and there...at 100k, and assume you do 20k a year so two yearts and 40k miles later, you could find a bunch of stuff that needs attention.
I'd NOT pay for any maintenance plans- find a good independent mechanic, roll up your sleeves on the forums, and figure out what needs to be done. ATF change, oil and filters, fuel filter, coolant, brake fluid... all are outside of warranty. And an indy can tell you of any little leak, defect, torn businging or boot, that you can then take to the dealer and say "fix it".
Hope this helps!
Keep it as simple as possible...but no simpler.
