not all of there parts are pricey most of the stuff is pretty reasonable, you do find a few things that are WAY out there but most of the time they're good. I have seen the sums done before in sales training they're not cheap to buy but cheap to own.
not trying to say they are the be all end all of 4wd's but dollar for dollar pound for pound taking all things into account they stack up well. hence why they are the best selling brand in australia.
