Congratulations. That's a great deal. Now just go over it with an even finer tooth comb. Check the original delivery date to see if it will hit the 3 years sooner than the 36k. The LCAs can be very expensive if not covered under warranty. Sadly I know this from personal experience!
Whenever I silence a noise my car is making, another one, that was masked by the first becomes apparent. The only universal repair is to dramatically increase the volume of the radio, purchasing a good aftermarket subwoofer and amp if your car also suffers from as yet undiagnosed clunks or vibrations.
