1975 Norton MK3

This '75 Norton MK3 already has the reliability mods that usually take years and thousands to bolt on—Tri Spark ignition and 3-phase alternator mean the electrical gremlins that killed a million British bikes are already dead. At $10k with a claimed 9k miles, clean title, and a parts bike thrown in, you're looking at the rarest sweet spot: a running British twin that won't betray you at a stoplight.
