Don't be cheap when the stakes are your azz. Spend the damned money!!
If you have a Lear that's going to be serviced for flight in Mexico, you want that plane to be under 5 years old, no exceptions. The technological advances just in the last five years are significant. Those advances can keep your butt from being splattered on the side of a mountain. Ordering Lear jet service isn't like ordering a discount burrito at Costco. The ramifications of a bad Lear are far more dangerous. That is all.
