Ah - but you forget that cost to Durango is not the same as cost to you.
The shock standoffs for example had to be specially made, whilst a screw and some nuts costs literally pence if you buy enough.
Likewise making the mould for the plastic o-ring caps may cost a fair amount, but once made the more caps you make the cheaper they effectively become. In contrast the machined caps essentially take the same effort regardless of how many you make.
The result is that with those parts I'm sure it would be a lot more than £20-30 more because they make it much harder for Durango to make, and less profitable.

Anyway - my view on the quality of the car is that it is at least as good as many other high end models. Maybe not as good as a 410 (I don't own one so can't say) but certainly as good as the AE, Losi and Yokomo cars I've worked on.
But then I bought mine because its a great 2wd car, not because I wanted a 'luxury' model. Admittedly I've blinged mine up since, because the car really does deserve the carbon and alloy, but it doesn't need it.
