Yeah you'll trade out for used/broken equipment for somethin else that is used and prone for more breakage. If it ever fails, get a rebuild, it will be like new.
I'd still look for one with less miles.
200K makes any vehicle A HEAP of junk. Consider these things first:
Do you know how he drove it? If he even has service records? That he took it in for servicing requirements? Coolant Flushes ,Transmission flushes, His MANY oil changes, Timing Belt Changes (every 90K), Water Pump (Same) , etc.
before spending 9K and then another 2-4K for other critical parts when they go/Blow/explode
Keep lookin'
My 03' AC SR5 4x4 has 57K miles, many upgrades like 3 sets of Tires (Summer AT tires ,Winter, Offroad Mudders), Intake, Sound System, New Rims, New Coilover Shocks and TC Upper Arms, Rear suspension mods(Deaver Springs, bilsteins) A HUGE Tough Country Bumper, etc, and I would sell for 15K max. and I have proof of my service records at Toyota (the mileage done at;Coolant Flushes, Diffs , Transfer oil changes, Air Filters, etc.), ALL my oil changes (synthetics), and every receipt to show for the mods.
