Ah, so you can use the search function after all.
It's just a passing comment, about a broken ring gear, that happens to be on a BDR. Why you choose to make a mountain out of mole hill is typical of a BDR owner/salesman response. Let it go,,, take a pill, it's already been clarified that rear end gear failures are very rare, for ALL cars.
Here's the thing.
It's not cool that ANYBODY who would DARE say something that appears to be negative about BDR WILL result in a flurry of defense, bashing of the poster and a truck of load of personal attacks. "We" should not be bullied, intimidated, threatened or abused by BDR owners or sales rep simply because we say something they don't like.
And THAT, in a nut shell, is WHY, I wouldn't own a BDR. The official BDR stance is just to militant and aggressive with their product support.
