The only issues I could see you having are, a leaky waterpump, leaky radiator and bad starter contacts. You also might burn up a fuel pump if you make a habit of driving around on empty. Other than those issues, you might be better off saving the $2k you would spend on a warranty.
An extended warranty is an insurance policy. The warranty company has actuarial tables on repairs and
on average it's a bad bet and you'll lose money, but if you can't afford to absorb a big repair
in isolation then you should buy it. While the average total claims for the life of the vehicle might be $1000 and the policy might cost $2000, for every dozen people who never have a single problem there will be an outlier with a $5000 transmission repair or $7000 rear blu-ray player.
I bought the warranty because of the electronics. When the DVD drive in the Nav system in my Acura went out, the dealer wanted $3k to replace it. I didn't have an extended warranty and I balked at the cost (and ended up taking it apart, ordering parts from China, and repairing it myself), but the extended warranty would've paid for itself 2.5x over right there since most people wouldn't have been able to fix it. That vehicle had a lot of sensors that seemed to go bad as well (rear diff sensor, engine oil pressure sensor, two A/C compressor relays, etc) and if I'd bought the extended warranty I probably would have broken even
without including that nav system issue. The first week we bought our CPO LC the overhead rear entertainment screen wouldn't shut. The dealer did something to reset the screen position sensor to get it to close properly, but we were told if the problem comes back it would require a new unit (MSRP was $7,000).
If you're the kind of person that keeps the minimum insurance coverage and if someone backs into you in a parking lot you knock out the dent and buff out the scratch yourself then you probably won't (or shouldn't) buy one. If you're going to immediately mod your rig and take it offroad, you might want to save the $ and put it towards some mods instead. But if you keep full comprehensive and collision coverage on your vehicle well after you've paid it off, or if you don't have a $ reserve to handle a big repair if one arises, then you're probably a good candidate.
