I'd like to see some empirical evidence about failure/repair rates of dealer inventory cars that are test-driven before sale vs. those that have only transport miles (i.e. > 10 at sale). That would tell us a lot about whether its possible to "do it wrong" because lord knows, I've never been kind to cars I've test-driven.
On my SRT8 that I bought, it has a peak hold for lateral acceleration in G's...... it showed .94G's to the left and .73G's to the right when I bought it. Someone enjoyed it before I did.
