If you do a lot of road trips, the gold plus seems to be very useful. Otherwise, you should consider whether the $1,250 Classic warranty is worth it or not.
Free Basic Warranty: For approximately the first three years, Subaru covers your car bumper-to-bumper
Free Limited Power: For roughly the first five years, Subaru covers your engine and trunk
In terms of motor cover, you are only paying for two years. However, the gold plus covers the ancillary components that the limited engine does not offer, and of course other benefits.
Another way to look at what you’re paying is that you’re betting you’ll keep the car for 5+ years, while the dealer is betting you won’t.
