I looked at two S80's today, one a 99 w/142k clean as a tack, BUT, it shuddered on take off and coming out of left and right circles. revved in RPM on one shift as in neutral,left off gas and it shifted.
Didn't always shudder on take off but always coming out of circles.

After a short run I shut it off to look it over, on restart white smoke with a tint of blue boiled out for a few seconds. Real heavy smoke, it didn't do this again after another short run. Price 5K.

My guess is a bad trans. and turbo.

Number two was a 2000 t6 w/152K, not as clean but would clean up real nice, It shifted as it should but was a little hesitate on throttle before turbos kicked in.

It was scheduled for dealer service on a recall. Price 4K.

No records on either, both Colorado cars no rust, no dents ect.

Any advise. Smedley

 

Private party called back on the 99 S80 T6, had taken it to her mech who found the trans. fluid was low, added to mark and now no shutter. Smoke has not returned ????

 

If trans fluid was low, I wouldnt touch that car.. these GM trannies are notorious for failing and with such high mileage, something as simple as low tranny fluid could be enough to begin the death process...
You have to question as well, why is there low tranny fluid? It does not tend to burn off quickly and there is something like 12 qt, so either the fluid had not been changed in a VERY long time or there is a leak, neither of which you want to deal with..


check out this one, tell me what you think

however, I should tell you that 2002 + became more reliable, so if you have the extra $$ spend it

 

Out of those 2, I'd take the 2000. See if you can get it for less, then you'll have some cash left over for maintenance and repairs. Plan on spending a lot of time or money to keep it up.

 

Of the two, go with the 2000.

 

Look at the link I sent, to me it looks a much better deal than your 2000. Not sure how far it is from you but I searched for places near to Denver..
