I saw this earlier as well. I really hope it is true. The ATS has pretty much got nothing but great reviews in comparison to the 3 series. Even with the 3 series coming out on top in most articles the reasoning behind the results are something that GM can easily fix in most cases, hopefully they are listening. The platform seems to be done right, especially compared to most of their overweight products.
I previously owned a 1998 Regal GS. Although its not the first performance Buick that comes to mind when you think of Buick legends...it was a great vehicle that was quick, reliable and fulfilled the needs of most people looking for a nice luxury vehicle...with the exception that most people weren't shopping domestics at that time. I loved the car and it treated me very well, it still has a small following of enthusiasts who modify them along with other performance oriented W-bodies.
The current Regal GS was a rather large disappointment...heavy, fwd and under powered. When the Regal GS was first announced and GM was touting the performance it would provide, being based on the Insignia most people thought we were going to get a full fledged Insignia OPC with a tri-shield...little did we know we'd get a vehicle with the looks but not the power to back it up. Even though I would probably consider a used one, I am hoping GM learns its lesson and builds something that will bring new car buyers to the brand and that this ATS based vehicle will become a reality.
That picture that goes with the article looks awful btw...
