3k to get a mopar textured top
You're close. $2400'sh depending on how cool you are with your nearest MOPAR parts dealer.
Also, there are other options.
Smittybilt makes a hard top now that is two-piece for about $2200.
And in the $3k range, Wild Boar's top is pretty cool.
Here in Phoenix, the going rate for an OEM unlimited hard top in good condition is between 1800-2200, depending on how fast you're looking to sell it. There's two on Craigslist right now brand new off 2015's for $1800 and $1850.
Unless you find someone who is dead set on finding a white painted top, you're gonna have to sell it cheap. And most people I know with painted tops, aren't the type to look to craigslist for them, or drive a couple hundred miles to buy a used one from a stranger.
See where it goes on ebay. Who knows, you might sell it.
