Models still powered by strictly port injection engines (muscle car, vehicles, Japanese)

From what I could find it looks like the only vehicles still being equipped with port injection engines are a few muscle cars and the 4Runner (possibly Tundra as well).
Am I overlooking any other mainstream models???
The current CR-V fiasco got me thinking about this even tho the problems they are having seem to be exclusive to Honda rather than updated fuel injection methods in general.
The Honda Civic LX and Sport are still port injection. Toyota uses dual injection, so it's both port and direct. I have a 1.5L turbo Civic and have had no issues.
Toyota is very conservative in their manufacturing (reliability is top importance to the brand) and uses either dual injection or port injection. All of their hybrids are still port injection.
I have to admit I haven’t been paying attention to this topic in general but I was under the impression that port injection was still sort of SOP for most manufacturers except for some very high CR engines.
Port injection engines can be reliable, as they don't have carbon build up on the injectors, like direct injection systems do. Honda has a few left, the new Insight Hybrid is port injection, and few other models. I figure life is short, so I'm going to enjoy myself and get the Civic turbo direct injection. I drove both to compare and it's a lot more fun. Just got to put that top tier fuel in, with the detergents to keep the injectors clean. I've only filled up with Shell since I bought it.

Top tier fuel won't do anything (or anything you put in gas tank for that matter), it's the backside of the valves that needs cleaning not the injectors themselves and the fuel does not hit the backside of the valves with DI.
Another downside of DI that most people do not talk about is the exhaust gas from DI engines. Those are tiny enough that our nose and lungs cannot filter the particles out. We are poisoning ourselves to meet the stupid CAFE standards. Something to think about when you are stuck behind a car with a DI engine.

On INTAKE VALVES. Not on injectors. GDI engines suffer from carbon build up on intake valves. this is why Mighty Yota does auxiliary injectors in intake. To flush it all off.
Btw, there already are reports on Honda GDI engines building up carbon deposits on intake valves after 70K miles. It's just that GDI engines in Japanese and Asian makes are rather so new, that few have that much of mileage collected. Report I am referring to was for a Honda used as taxi cab, so it raked miles fast. Honda does NOTHING to prevent that build up.
Look at the first GDI engines, which were VW. That was a plague.
