Keep the 8v mate, keep it mint, undercover or summat?! Is the VR6 loads quicker? Damn, I want one now that Ive seen this.
What bits are you swapping anyway? Im hoping the steering wheel and rear lights for a start. 
Wheels, smoked indicators and joeyed headlights. Don't want to completely break up the 8v. The rear lights actually look nice on the motor in the flesh and are staying for now

As for the steering wheel.....I will find a replacement first as I don't want the standard wheel in there as it will not really match the rest of the interior so for now that stays until I find something else I like.
I am not convinced I need to sell the 8v but it's a shame to leave it sitting on the drive all the time although if the fuel consumption in the VR is too high then the 8v will be the works car and the vr for weekend.....who knows ??
