$30 for trunk and lid is a good price. I need to CAD and print myself a new trunk lid, a friend works in industrial design and took like super high quality scans of the original trunk lid and has them 100% to OEM specs. I think he wants like $40/lid or something. But to me a 30 minute CAD job with a pair of calipers and printed on my Ender3 is good enough.
Hard to tell from the pic, those switch bases aren't aluminum are they?
