Also you may fail come MOT time with aftermarket HID's, due to no self levelling sensors and washers. Incidentally, does anyone know why all xenon equipped cars need to have headlamp washers??
I think if you can stretch your budget, get the options you'd like that only come from factory. Things like satnav is alot cheaper to retrofit yourself.
I made the error of not buying the MFSW, and i sooo regret it.
Also because the Golf has the homecoming lights, it looks fecking cool when you park up at night with the blue hue when you unlock your car. Certainly for me it turned some heads during the X-mas shopping period. Then again, i'm a poser
