First Time Buyer! Wisdom would be greatly appreciated! 2000 SR5 210,000 miles $6k

I'd jump on it, if it were me!
These days, that's an outstanding price. How does it run? What's that clump of stuff on the fan?
When was the last oil change, timing belt change, when was last time the drive line was lubed, the last oil in the differentials, or tranny change? When was last time the coolant was changed? When was last time the brake fluid was flushed/bled? When was the last time the plugs and coils were changed? Even the last time the hot water control valve was replaced? How thick are the front brake pads? How does the LBJ's look? How does thee frame look? Is it rusted?
Are there any warning lamps on on the dash? If so, what codes are showing?

All this stuff matters. You might even be able to get some cash knocked off the price if the regular maintenance has been neglected. If not, that's a great price.

Just my opinion. I am NOT a professional mechanic by any stretch!

The rear bumper and hitch usually rusts out first, that one is fine.

 

What he said!! How does it drive, given no apparent issues? Been in an accident?

 

Those pics look pretty good for that price.

 

looks in good shape...check underneath...for rust.....6k isn't a bad price...unless it's a rust bucket, etc

 

It barely qualifies as being broken-in yet. It needs another 200k, so get it.

 

Great engine. Truck looks clean as heck. Please tell me you bought it!

 

And if you did buy it, congratulations! If the radiator is original, replace it right away to avoid a transmission failure.
