Not seen the "Tango Red" colour around anywhere so i'm tempted by the uncommonness of it
I have one

I went from the 1.2 GP to the 1.4 2012 GBT, it's the 1.4 8v 77hp engine in it, it's not going to win me any races, but it's perfectly capable under any conditions I've thrown at it... and seems a good balance between power, economy, and not getting sodomised by your insurance company.
One thing I'd say, if you're buying new, get the sports suspension (unless you plan on changing it anyway) - it's a godsend, the 'standard' suspension is just WAY too squidgy in my opinion, it rolls too much.
Oh, in comparison to the MK2(b) I had before i'd make the following observations:
Steering, much 'heavier' than the MK2, and goes where you want it to.
Throttle, very responsive. MK2(b) is slightly quicker from a standing start I think, 2012 has better gear ratios (I think so anyway) - sounds 'gruffer', doesn't whine.
Brakes, more responsive, much less vague.
Handling, found the MK2(b) handled corners better than by GP, but the 2012 with the firmer suspension is better than either.
HTH.
