Hey, this is very pre-emted as it will be at least a year before im getting either.
Basically if it was to be the gsi it would be a year before i got it or if i chose the more expensive RS i would wait around two years before buying/affording it.
Just musing over what i like about both cars and love my astra just now. But i just think the RS looks like more of a pedigree car.
The big question is, what would you choose?
