RJ automtoive have come up with this for the astra G:
That is fitted to another astra-sport members car and another one has been ordered by another member
It does away with the lock on the boot for added security and a nice modding detail. It comes with a solenoid kit so that you can pop your boot open by the button or by your alarm if you have a spare channel.
The cost is as follows:
For the handle in primer and the solenoid kit inc full instructions =£160.00
For the above plus fitting (button release) and painting = £210.00
They are willing to paint it to your cars paint code as well and mail order it to you but you will have to call to arrange the price as it will depend onm paint.
If you want any more info please give them a call.
