Since buying the car I will list all the styling changes here

Exterior Styling

I have replaced the rear lights and centre panel with 99 spec ones
Rear bumper indicators have also been replaced with clear lenses for a fresher look with the white bodywork

Interior Styling

The leather gear change gator, handbrake cover, and centre arm rest have also been changed for a White stiched Italian leather replacement.
We have gone for a new steering wheel with buttons to use with the NOS that is going in. I really liked this MOMO steering wheel and although it was pricy it did not look like piece of crap that some kid would buy from Halfords and fit to his car.
