Full restoration on a rotisserie spit, most parts on there are new, very good second hand or refurbished.

The car was bought in 2011 & was fully stripped, the sunroof was rusty & spare wheel well was rusty too. 

They were both removed (to flat floor the boot ) & install a genuine carbon fibre roof - carbon-delight.
