Cusp

Sad isn't it. I went to a yard looking for a radio for my 2001 Ranger. They had a unit on their greasy electronics shelf virtually exposed to the elements. It was dirty with grit inside. For this they wanted 60 bucks. I put in a bid for a unit on ebay which I won for 10 bucks and another 10 to ship it. It was prestine inside and out. Had the radio been in the same shape the eBay one was, I would have paid the 60 just to have it while I was working on the project. How do those places make any money at those prices for what amounts to neglected crap.

Same way around here. Junkyards want waaaay too much for their junk.

Try some plastic headlight restoration
product available at your local parts store.
Avoid the rouge, its way too aggressive.

The cap can be sourced at the dealership.
Or can be replaced with a push to start button
for abot $100.
