Chevy dealer I worked at sold a new Blaser and a torsion bar broke on the freeway so the dealer bought it back and installed a new one. It was resold as "new" and it broke again a second time months later under the 2nd new owner. The dealer bought it back again from the 2nd guy when they realized there was something wrong with it. It sat on the lot for a little bit and then a GM regional rep showed up, looked at it, and then scheduled it to be hauled away someplace. Not sure what happened after that. Could have been put together with an alignment issue and something was in a bind that was making the bar break? Who knows...
