Small update on progress, in preparation for the MOT I was checking the rear suspension and noticed one of the ball joint covers was perished, no leaking grease but cracked and wouldn't last much longer. First went to Halfords this morning to see if they sold anything, no chance, but did see a nice Y reg GTV ending something like CGO, Alfa Red. Got back and remembered I had a used rack so salvaged a boot of one of the track rod ends, perfect fit. It was a bit of a bummer replacing but cost nothing and the joint was fine and was good quality TRW one. Here it is before tightening up to 100nm.
I reckon it's now worth a go at getting an MOT, bonus too, got another quote for insurance and it's even cheaper again so will be getting the insurance sorted then taking her for an MOT.
