Let's do this by manufacturer as these are not European Mfgrs anymore as the Big 3 have bought most of them:

3 DCXs

3 Fords (Well at least Ford is making lower quality cars under different makes so they can they are making an improvement)

2 GMs (not surprised...figured the grand prix's chassis, engine etc was so old they'd have kinks worked out of it like 10 year old designed and never changed buicks)

1 VW (i'm surprised only one VW on this list especially with VW a perennial bottom dwellar in quality reports)

1 BMW (most likely on the list b/c of the i-drive and not being poorly built as often argued by someone here)
