I wanted some new bleed nipple / screws for my rear drims on my Fiesta RST £3.20 They are mild steel and suffer from the dreaded tin worm too! I think my next set will either be titainium or marine stainless.....
I doubt they cost more than 10p to make! - big business and commodity prices are going through the roof.
Last May I needed a MPV as family came over from abroad for a month, so tried to hire one... cheapist quote £780! so I bought one for £1310 spent some time fixing door handles and £35 on new brake pads £30 on insurance, then sold it for £950! Saving me £355... Just goes to show do it your self use, small businesses and you save a fortune!
