Update today....
.... It's been a long/good/rewarding weekend. Really happy with the work that I got sorted out on the car. Total of about 8 hours over the two days. Probably quite slow work for what I've achieved but there was a bit of head scratching working out how to get the cigarette lighter out of it's housing.
In basic..all carpet,sound deadening, sill trim, the lower gear gaitor and dash surround has all been removed.
Guestimating I reckon there must be a good 20kg saved from everything that's came out. I couldn't believe how much sound deadening there was to come out. I also noticed how much easier it was to fit the seats back in without the carpet in. Had a right game last year getting it all lined up, but went back in a lot easier today.
Had a quick blast once it was all sorted this afternoon, and I THINK it feels a bit quicker/responsive. Could be a placebo though
