Oh you must have stories, I want to hear themReminds me of the fleet of Amphicar's I used to service. Pop quiz: what do you get when you combine 1960's technology, West German engineering, and the desire to create an amphibious vehicle? A recipe for disaster. While the cars did come from the factory with approximately 2 dozen grease points, the sealing tech of the day was no match when faced with water intrusion.
I'm not exaggerating when I tell you all: When kept on land, the things were "decently" reliable. The second you took them for a dip and back out, all (despair) broke loose. Prop bearings took on water, wheel bearings took on water, brake linings refused to dry out.
I still wonder what could be possible should one decide to "modernize" an Amphicar. There's a surprising amount of room in the engine bay for a small 4-cylinder engine, the chassis is relatively easy to service, and should one decide to properly seal the running gear and body openings there's a real possibility of a fun toy there.
For those that don't know the vehicle in question, here's an old MotorWeek clip where they actually showcase several of the cars I used to work on:
