Find examples of where I've stated the RX8 is better than the DC2. All I've said, is that it isn't worse, or rather the DC2 isn't better. Perhaps you ought to go back and read the OP, where I categorically state that I couldn't choose between them.
Abuse leads to premature wear, I don't see how it leads to ruining a car. I do want something that isn't so expensive that I have to worry about ruining it though. That doesn't mean that I'm willing to just throw that money away - all well and good, it'll still be nice to be able to sell it on with little loss, should I ever choose to do so.
One example of the above is taking it to the 'ring or a track day. There is a risk that if I crash it, or something crashes into me in either situation, that I will suffer a total loss. That isn't to say I'm banking on that happening, but £5k is more than I'd be willing to loose, £3.5k isn't ideal, but it isn't going to be the end of the world.
I still don't see how you feel yourself in the position to be able to lecture me about my automotive or financial decisions.
