I'm a recnet GTi owner '08 MKV & I loooove it!
Personally, I like the interior of the 5 better. Just for the sake of having the "latest & greatest"...I'd save the balance & treat yourself to a holiday or something....
Anyhow - I bought mine with these options: mocca heated leather seats (which look fantastic against the TORNADO RED), sunroof, xenons, parking sensors, DSG...
For me I WANTED a SUNROOF on a RED GTi : the others are luxuries which I've grown really accustomed to very quickly!
I was at the right place at the right time!
