I ddn't mean to offend anyone by my anti-T top comment.
These are my opinions from personal experience:
T-tops are cool...I own a G-body monte ss w/ t tops. I wanted that car because of the t-tops. But the thrill quickly wore off. First of all, where to store while driving? Them in the bags in the trunk....moving around, especially when turning corners...a nice way to dent the driver's side quarter panel from the inside and/or damage the tops. Second, mine leak even in light rain...annoying. 3rd, the seals...when they dry rot...they are expensive to replace. 4th...they sometimes rattle while driving. 5th, the area under them is usually rotted/rusted because the water sits if the drains are plugged. I'm probably forgetting other things that bother me right now...maybe no shades for them w/ these cars(mine are tinted though)...security reasons(even though they'd just pry the window)...the metal roof behind my T's to the rear window is really thin metal(maybe a cheapo design?).....blah, blah................
All the above are my problems with a STOCK car......add some mods(especially to a GN)...and the solid roof adds rigidity, etc.
I'm not even a fan of sun roofs on cars...my daily driver has one...and I rarely open it. Also keep the shade drawn across it to keep the sun and heat out of the car anyways, so my ac is colder.
But, to each his own...................
