My VX took over 4 years to reach 30k, so my original warranty ran out long before the "BIG 30K (ka ching) CHECK OUT" ka ching I spent less than $100 on fluids and not only checked, but replaced everything I could get my hands on. Also got a set of greasable bar bushings. VX has got to be the easiest vehicle to work on I have ever owned. Heck you don't even need tools to change the serpentine belt And with all that ground clearance we have, heck you only need to lift it when you remove a wheel.

$500 is a lot to pay for checking, I suggest you buy the needed fluids, get a little dirty, put some wrench marks on your "CHECK" bolts, and keep all receipts. change your fluids yourself as often as you like, but at least as often as suggested, and save a great deal of money.
