Gotta say I did this with my cos and its certainly the best way,pointless chasing a rotten shell as unless you've got the patience of a saint and deep pockets you'll be worse off.
Plus buying fully trimmed means you either get a ton of spares or a few bob back in your pocket.
£1800 will only just about cover a respray on any shell let alone a rusty welded up dog!!!!
Great bargain this
