I have owned quite a few Gbodies, I always thought they had great styling for their time period and even now I think if they are done right they have an eyecatching look.
To me I liked that they could be a really nice more modern cruiser compared to the A body platform since Gbodies had many options that could be added and almost all of mine came nearly fully loaded and about half with a roof option.
I liked that they could have AC, power steering ,brakes, tilt column, power windows, locks, trunk release, sun/moonroofs, t-tops, cruise control, rear defrost and later models even an overdrive trans.
I always liked their cloth interior with either 60/40 pillowtop seats or buckets and console.
The full frame/rear wheel drive platform makes a great foundation to build on.
Other than the GN the only real turn off for me was the lack of power and I always thought the Monte SS looked Badass but it was a "sheep in wolf's clothing" so since I couldn't afford a GN I finally settled on my Monte CL to build up the way I thought a Monte SS could look and also have some real power under the hood.
I think this is a generation of body styles that still have the potential to be something different and are not at the point where everything conceivable has been done to them already, nothing against a 69 Camaro but it's been done to death.
I've looked at other body styles like the A-bodies and Nova's which I have owned a few of both and have considered second gen F bodies but I always come back to wanting a Gbody, it just feels right when I am driving mine.
