And the Charger's Natty Lite version, the 392 R/T Scat Pack. Somewhat like their truck counterparts, I'd expect the engine and trans to hold up long term while everything around the drivetrain ages to brittle state.
I can't imagine holding onto any of these high-boosted or high-strung performance sedans beyond 6 years/100K, but the domestic versions are probably the easiest to wrench on and obtain parts for long-term. You could stick with boring and reliable via Lexus GS-F, but there's no redeeming quality in that car, to me, beyond its exhaust note and use of a normal-aspirated V8. It's otherwise tacky looking, performs at the bottom of its segment but probably reliable for no other reason than kaizen and Toyota.
No, you can't change my mind, since the LF-A is no longer produced, the Lexus F-line is all fail. Almost as cheesy as the overt-English-accent narration used in their commercials.
