I'm not an operator, but I've worked on many so my two cents:
Barring any issues, the price seems right, on some conditions.
I'm partial to Bobcat's probably because I have a lot of experience with their quirks and tricks, but the T180/190 is probably my least favorite current production model.
I think it all boils down to size, and the perception that this machine looks more capable than it really is. It looks like a tank, and I think folks tend to overwork them, and they end up broken, seemingly more than the larger Bobcat CTLs. It is only a 1800 or 1900 lb. class loader, after all.
If you keep in mind that it is basically an S185, or 773 with tracks, or a more stable platform with better go in the mud, and don't try to do things that would be better handled by a large-frame T250-320, then it is a good machine with a bad rap.
I would absolutley NOT buy any used Bobcat with SJC, and I almost hate ACS. I would not buy any new SJC or ACS machine unless I was at a point where it was economical to buy every two years with extended warranty, like a HERTZ or a majorly big construction outfit.
Being in this forum, you're most likely a DIYer. If this T190 is a Joystick machine(SJC), it is my opinion that it's a money pit, and for $14K I wouldn't advise it if you're planning on keeping it and tinkering with it yourself. Almost as much so if it's an ACS (electric over hydraulic hand and foot controls), but not so bad as the former.
If it's a mechanical foot pedal machine that starts and runs well, that's a seemingly good deal, and keeping in mind this model's limitations, I'd say go for it.
But it's all subjective, man......
