Does the saturn sky and pontiac solictise handle like the new opel GT and what is the boot capacity in litres?

i know saturn is an amrican crap copy of opel and the pontiac is a copy of the opel with a slightly different design|||Saturn Sky and opel GT are almost exactly the same down to the trim. Pontiac Soltice and Soltice with the turbocharged motor. There are companys putting in the 6.0 liter LS-2 motor and Transmission. Do not buy this car if you want any BOOT CAPACITY! about 3 rugby or foot balls can be squeezed in the boot. And they are all the same UK built car.|||They do handle the same. They have the same chassis and about the same weight. I am not sure about the size of the boot in litres, but I kno you can fit 1 big suitcase.
