Best way to give it a good clean.
I have mine now for aprx 3 weeks , and this is what it looks like know
Has been washed 3x times polished 2x - outside, then started to clean the inside, so much sand I decided to strip completely and clean properly.
End result - I tried to ensure that all wires are neatly in place and glued to stay in place

(sound system, arial etc)
I fitted 12v plug in rear for fridge/freezer, and 2 seperate 12V points for lights, dvd or what ever else is required.
Getting alarm and central locking as we speak - and being stripped I will be able to see exactly what they did
Next is the wiring on the electric windows - still praying for good auto leckie to do this.
Re-upholstiring all the door panels and rear door panels and will be putting in new carpets. - question what can I use as sound proof as the old carpet is vrot!!!
