On the "other" forum, many members have bought the ZHZ's and only a few have had issues, and a few with minor interior scatches, but most of these items are fairly cheap to replace. As most rental vehicles, the upkeep is good, and most have the GM warranty work done on a regular basis, including all the TSB's completed. There were a total of 500 coupes and 375 convertibles built for North America in 2008 and 2009. There is a dealer here in Mississauga that has about 10 of them for sale, one of them with about 42k on it for only $36,995 CDN
Most buy them because they are cheap in comparison, and then remove the stripes and fender badges, so as to not be perceived as renters of the car. There is a big demand for the ZHZ stiched interior appointments including the floor mats, seats and center console arm rest. The outside appointments are the full length spoiler (common) black stripes (availale at GM) and the rims (available at GM) the badges may be hard to find from GM, but there may be some new ones available. They can be copied, although that is against the law
There are for sure fewer than 500 coupes available as some have not endured the abuse, as the attached photo shows.
