2014 Prius v w/ 175000 miles

After being rear-ended by a freightliner just over three weeks ago and having my 2009 Toyota Corolla totaled, I am now looking into purchasing a used Prius. Preferably 2012 or later (would also settle for 2010+), but also below $10,000, which leaves leave me with very few low-mileage, non-salvaged options that aren't from a shady dealer or a bit beat up cosmetically on the inside and aren't lacking a bit in extra features. I've read the thread and articles on the Prii that have reached the 300,000+ mile mark and it gives me some hope. My Corolla had 156,000 miles on it before the accident and was still going strong, and from what I could tell, still had a long life ahead of it before it was cut short; so I am a believer in Toyota's vehicle reliability.

I've found myself checking into a great looking 2014 Prius "v" (lower case). Seller is asking $8800, which is below my budget. Single owner, clean title & no accidents. Sounds amazing.. The catch is that the vehicle has 175,000 miles on it. At $8,800 (potentially lower through haggling) is it worth the risk? I've checked into the car's service and maintenance history and the driver has religiously gotten his oil changed every month or 10,000 miles at Toyota dealerships. At 134,000 miles they changed their spark plugs and had their front rotors resurfaced by Toyota. At 115,000 they had their fluids replaced, and at every visit after crossing the 150k threshold they've had their battery tested. The last service update from Toyota was at around 172,000 miles where the driver "declined oil seals / gasket repair"... Should I take that as a sign to turn around and run far far away? I've read estimates of the repair being anywhere from $650 to $1600, depending on what seals or gasket need replacing, and by whom (smaller mechanic, or through Toyota itself). At 175,000 miles and only three years old, does this car have more life ahead of it or should I look elsewhere?
