While some may use/recommend an aftermarket gauge/sensor for accuracy, there are still many that may just want to keep it stock (looking). Most don't want their car to resemble a fighter jet cockpit or to modify stock parts to mount and route the components of an "accurate" temp gauge....assuming a mechanical gauge here. An electrical gauge would still require something modified to mount the gauge and run the wiring. While you may find an obscure place to put a gauge that could be easily replaced, it still leaves some piece of the interior that would need to be cut, hacked, drilled or modified from stock...i.e. A-Pillar or dash face. The blur's car is described as "stock" in his first post and AM gauge/sensor may not help him much.
Blur - assuming you are trying to keep your car stock and living with a gauge that may be off somewhat, what things have you done to clean up (flush) the cooling system? I would recommend a full flush and clean of all components to the cooling system...,rad, reservoir tank, heater core, hoses and block. Once that is done, be sure to bleed the system and then see how your factory gauge responds.
If you suspect a problem with the gauge and/or sensor I would recommend that you get an inexpensive infrared thermometer and see what temps you are actually reading at places like the Tstat housing, water pump, block, etc. once you determine for sure the issue, then you can proceed with trying to correct the issue. Maybe the temp is actually fine and you just need to adjust the gauge (move the needle) or take into account it just "reads" high and factor that in. Just like having a speedo that is off by 5 or 10 MPH.
