Yes its the best option .
If you buy the parts seperately..its not good sense financially . I've seen things like instruments and dash panels and switches on EPAY , sell for ridiculous money .. almost for the cost of a whole vehicle..
Some people buy a wreck, pull it to pieces and sell everything seperately.. Go to any car wreckers and you'll pay outrageous prices for stuff they have bought for almost nil.
You can buy a new XF Falcon bonnet from Rare spares for $950 ( their current price list ) ... or buy two or three whole cars for the same money
