I will go ahead and be the odd man out, sort of, for most of my thirty plus years of brit car ownerhip I did not worry about grease or the appearance of the mechanical bits, when I started driving the Healey or MG or Triumph was the car that got me to college or school or the bar. If it was broken I was usually trying to get it back together so I could get where I was going.
Also the grease would inevitbly and quickly find its way back onto the daily driver and I noticed the only areas not prone to rusting away were the greasy bits.
That philosophy continued until recently, I am takking the cleaning all the parts, painting and polishing on the TR250, I can't say I have gotten to the point where I feel compelled to do this, and I can't say I enjoy it, in fact it slows things down, and I have learned the generic Ace rust fighter enamel and Rust Oleum gloss black and flat black is that the name brand dries much faster, which is a very good thing.
I still feel to some extent that the shiny bits on the outside should be shiny, and the greasy bits on the inside have a job to do and as long as they are doing their job right if they get a little dirty doing it who am I to complain?
I do save old parts, I do not worry about cleaning them other than to make sure they are not leaking fluids, if I have a compulsion I need to get over it is saving old parts, once agian coming from when I was young, not a lot of money, and LBC parts were getting harder and harder to come by, I have recently started to throw away replaced brake hoses and pads, I always knew I would never use them again, but the thought that some day the car woudl need something right away and I couldn't get it and a general dislike of wasting anything has kept me somewhat of an overpacking rat.
