Mr. dB said:The retractable hardtop is gonna add at LEAST 300 lbs.
But at least you can justify these 300lbs unlike the Solstice which is just overweight.
Btw I doubt it would add 300lbs. While not being retractable, I remember being told that the removable hardtop for the S2000 added only 45lbs. So a retractable would be closer to 150lbs maybe 200lbs max.
