Are you willing to gamble an amount that could be equal to or more than the value of the car? If so, then buy it today and end of disucssion. Otherwise, a PPI is meant to mitigate that risk to a reasonable extent.
For example;
First, let's start at the low end of the cost spectrum - the air oil separator, water pump, and/or battery/starter might need replacement. Unless you know what to specifically look for, you'll miss this and end up with repairs anywhere from $250 to $1,200.
Next, let's consider some mid-range repairs like suspension components, bushings, wheel bearings, CV joints, and/or a/c compressor. Unless you know specifically what to look for, you might end up with repairs from $500 - $2,000 in addition the the cheaper stuff above.
Last, let's consider the worst case and consider the engine (it has a $2,500 CEL right now), transmission, and/or clutch. What if that $2,500 CEL turns out to be something more serious? What if you don't happen to notice that small glitch when shifting from 2nd to 3rd gear indicating that the 3rd gear synchro is worn out? You could easily be looking at $1,500 - $5,000 of repairs in addition to the cheap and mid-range issues above.
At the end of the day, its your money and its your choice, but spending $300 on a PPI is the best money that you'll ever spend.
