Your wireform ramps can be re-plated. Mike Chestnut does great work on that, very reasonable for the quality level of work.

The top of that scoop under your Borg ship looks like someone has re-welded the weldment at some point and their fix is oxidizing/corroding. The scoop is available as a replacement, not a biggie.

Superpins can be tempermental. Be sure to check the boards in the backbox for signs of corrosion or someone's amateur attempts to repair them. Look for signs of bad solder work, lots of extra jumpers, etc. The auxiliary 8 port driver board in the upper right hand corner of the backbox is often a source of trouble. You can get better replacement versions of that from Rottendog if it has issues.

Under the playfield:

Check the wires going up into each canon. See if they show signs of being twisted, or worn insulation. If they're all inside shrink tubing that's a likely sign that someone has upgraded that part of the wire harness as it's a typical failure point on STTNG.

Check the subway under the playfield. Those often crack and break. (for that matter, the three ramps on top of the playfield often crack and break as well) All of those ramps are readily available but they're not free and that should be something taken into consideration when you haggle price on this pin. Replacing all three ramps and the subway for example, would cost a bit over $400. (ramps and stickers)

It's a great pin, one of my favorites but as previously mentioned by someone else, it can be a pain in the ass to keep it working properly. Nothing you can't manage, but definitely more than a lot of other pins.
