Another good piece and the theme is close to all sufferers of Zeditis. What it lacked in Dan's lads mag style it more than made up in poignancy.
In terms of the question posed, a day doesn't go by where I don't appreciate the headunit/amp/speaker mods I've done, I'm also in luuuurve with my refurbished steering wheel and the dipped door pulls. The common theme being I interact with all those things every time I drive her. Some things are just bloody handy, reverse cam being a good example of a full on practical mod.
Of the mods I don't tend to consciously appreciate, it's mainly the styling ones. I notice when they go on that it "looks better and also different to other Zeds" and that feels satisfying, but thoughts soon turns to the next little bit of rice on my list.
Enjoying these articles, great idea
