This GT is overpriced. Why pay £28k for a 90k mile car when £33 buys a 40k mile car? The re-spray of the doors, sills and rear wheel arches alone will eat up a fair amount of that difference.
Having owned a GT a GT-S and a GS to me the GT is more common, bigger, slower, heavier and more costly to maintain than the GS. The only advantage is that its 2 years younger than most GS's and the model is still in production so its more difficult to age. Some people might prefer the looks as well but this is a matter of taste. With the GT ending production this year and the Alferi coming I think the standard GT cars will age quiet quickly and I can see them trading in the £15-20k range within 3 years. No doubt it will be hold back any chance of the GS rising for a while but longer term I think the GS will be the better car to keep. Just my own opinion which could easily be wrong.
