I vote to replace it with a used Chevy SS. Ok, they’re discontinued and I didn’t know they existed until I saw a video review of one. But I thought, hey, if I need a 4 door sedan - I’d like that 6.2 liter V8. Probably not as plush riding or roomy as a town car. But 415 horsepower / 415 tq, and 4 doors.
An Avalon is probably a much more practical choice. But…6.2 V8…
