Range 3: 360 / 1523HR
Range 4: 199 / 1370hr
Range 5: 4 / 1370hr

Total hours: 1538hrs
Thanks!

I wouldn't do it. Looks like its had two major money shifts, one at 1370 & one at 1523.
The level 4&5 are a deal breaker.

Statistically speaking, this car will probably be problem free. The question is do you feel comfortable wagering that risk with potential problems that may not be warrantied by PCNA. Like everyone says, there are too many good cars to choose from out there. Good luck!

Skip, any in range 5 would be a no go for me. There are many other unmolested cars on the market.

On one hand one hates to see overrevs above range 1 and to see overrevs in the higher ranges...
OTOH, the last overrev in ranges 3, 2, and 1 occurred 15 hours in runtime ago.
Even better (?) the overrevs in the higher ranges occurred 168 hours ago. At 30mph (average speed) that was over 5K miles ago.
Have you listened to the engine from a cold start? Have you had a chance to hear it idle, warm up and then had a 15+ mile test ride followed by a 15+ mile test drive?
If the overrevs harmed the engine the engine would by now be making noises, the CEL would be on (possibly due to misfires from one or more badly sealing valves).
But is this the best car you can find?
Sincerely,
Macster.

Thanks for all the responses thus far. I have not driven the car yet and will check for those item. I do have the option of buying an aftermarket warranty which would give piece of mind.

i love it when you chime in NVan! plus, these just give me more hope that my similar overrevs wont prevent the car from chugging along another 40k miles!
yep, not too scary at all. depends on the deal if/or CPO, etc.

If range 1 = 6800 to 7000 rpms (different ranges exist by type of car/engine) the a reading of 2709 / 1523 hr means that 2709 ignitions have occurred in the 6800 to 7000 rpm band and the last one occurred at operating hour 1523 - you don't know how many occurred at hour 1523 just that the last one did. Since there are 3 ignitions per revolution at 7000 rpm you have 116.67 revolutions per second so with 3 ignitions per revolution or 350 ignitions per second. Divide 2709 by 350 and it looks like at this reading the engine has been in range 1 (6800 to 7000) for less than 8 seconds. I think I got this right. Ranges 1, 2 and 3 don't seem to bother buyers - usually indicates spirited driving and bumping up against the rev limiter. Ranges 4, 5 and 6 are usually indicative of a mechanical over rev (missed shift) and depending on how bad could result in engine damage either at the time of occurrence or later on in the engine's life.
