Got an Ed30, it's not great on fuel but then it wasn't bought to be frugal.
Honestly doubt it will ever get sold.
Had it from new for 4 years, been tweaking the car a bit with mods the last few months, reckon it's just the right car for me.
Know I'm biased but think that the Mk5 GTi was a real class car, (esp Ed30 & Pirelli) and hope that 15 odd years from now, they'll look like a smart Mk2 Golf Gti looks nowadays.
Those cars had no 'safety' features bar seat belts and yet still exert a pull, especially if you used to own one.
Now a Mk5 with quite a bit of passive safety to it will likely be protecting it occupants to some degree when it's a 20 year old car so won't be old death traps.
So when we've all got hybrid/fuels cell/solar/Judge Dread style cars in the future and super unleaded is rare and expensive (V-Power £1.40 a litre will seem peanuts) - we'll all love the sight of a GTi with a nice exhaust note rumbling past.
Of course by then Golf GTi (Mk '12') will be a nice small hatch about the size of a Phaeton, 1100cc turbo..and John Connor will be the US President.
