oh no.... <brings out flame-retardant suit>
This probably isn't a good question to ask here: its going to degenerate into a "ricers suck!"/"domestics are a POS" thread, once again.
In all honesty, it depends on the models being compared. A lot. I think the domestics were sadly outstripped in the 1980s... but they have made a resurgence as of late (look at the new engine in the TrailBlazer, for instance). Now, they just need to get their interiors and fit-and-finish up to snuff... and realize that people are willing to pay a little bit more for a car that will still be running (and possibly look good) in 8 years.
