Agreed that the domestics have been doing FI for a while, although many of the earlier turbos (like the Omni GLH, Spirit R/T, Thunderbird SC, Turbo Trans-Am, DSMs, Regal T-Type/GN) were fairly niche-oriented cars. Successors like the supercharged Buick 3800 in the Grand Prix GXP and Bonneville SSEI brought it a little more into the mainstream, but these were still marketed as a performance bump rather than taking the modern everyday economy and reliability angle.

I never heard nice things about the reliability of the Corrado's G-lader... not that the 12V VR6 is a marvel of easy maintenance either, but people seem to prefer them.
