what year Corolla?
My buddy has an '03 Pontiac Vibe (basically a rebadged Toyota Matrix, ie: Corolla wagon)and there's a well documented "glitch" in that generation of Vibe/Matrix/Corolla,etc that the Odometer Stops @ 299,999 like he pictured above in the Prius.
Sadly I doubt his Vibe will make it that far.. it's around 250k mi now, but falling apart... litterally... the Driver's door is going to just fall off one of these days..the hinge bolts are actually pulling through the "A" pillar. it was wrecked and slapped back together before he bought it 10years ago, with 120k mi. had I seen it first, i'd have told him to steer clear of it, but, he's gotten 10 years out of it and put 130k mi on it.
