Not all mk2s have the wiring for rear windows and the poverty spec didn't even have electric fronts. I did both our mk2 s about 6 years ago, took an hour to do each car. On my ZS I took parts from a mint 45 that had only done 22000 miles before it was rear ended. I also got full leather interior at same time along with climate control parts. On my sons ZS I picked up parts from an earlier 45 but door cards were damaged, fitted tweeters in holes lol.
Got a mk2 sat outside my daughters with heated front seats, rear electric windows, parking sensors, haonda front interior light and Laguna rear interior light all fitted by myself along with climate control conversion. Been sat for 5 months as she has new Nissan SUV lol. When weather is a bit warmer and my back is up to it be scrapping it as she can't be bothered with it lol. Shame as it went through mot in August no advisories again but no market for these cars now.
