Trumpeters 1/16 Panther is a seriously nice kit. It has a few mistakes that superior modellers will point out. My opinion is that it was good enough as a challenge and a fine display piece. I did use some 'Aber' and AFV Modeller upgrades. These were not required but did add just a little more 'class' to the build.
In my opinion, the kit is a 4.5 of 5. There are lots of upgrades available for this kit. Depending on your budget and need for detail.
