very unhappy (insurance)

[xf ford ute]

Just got off the phone with 5 different insurance mobs enquiring about full comp for my xf ute that is nearing completion of its 3rd rebuild now with 351c, 5sp, 9", lowered, new interior, new paint (current standard bmw colour), etc. nothing to drastic, all legal and all engineered by a certified engineer, as a daily driver. Not asking to much in agreed price of $12,000, they knock me back because they won't cover the paint ( due to being metalic), also due to the amount i want to insure it for. I can provide full receipts for all mods and purchaces but they don't want a bar of it. I'm out of ideas, and ready to toss it all in. there must be somthing out there someone out there that knows something. Can anyone help.
