So after endless amounts of tinkering I have decided to take the gti off the road for a few months to sort put some nagging issues. It hopefully won't become a ground up resto! Really sort out the trim with new clips, replace some broken interior bits, some seals and depending on how hard it may be consider a re spray. I may paint it myself after some practice on some old panels. Getting rid of the auto is also high on the priorities list. I need to finish my kombi first so a quick tidy up is what will probably happen then later on a re power. Thanks everyone for answering my dumb questions!
