Good to see you working on something car related!
I have the hiab too but not found time to build it yet.
My son loves playing with the models and I enjoy building them so I have a cupboard full of the latest technic models.
The big excavator and Volvo loader are good to build and the gearbox in the green recovery truck is really clever how it works,I have 4 big motorised models to build if I can find time ha ha.
