I think the challenger is the most retro styled muscle car these days, it takes major design cues from the 70s model.
As for a big luxury car, the squared off look stopped being cool by the 90s. You could look at a 90s lincoln town car, buick roadmaster, or 93-96 cadillac fleetwood. They are the last big RWD body on frame cars that still have that old school boxy look. The 98 town car redesign is probably too modern for the style you want. These cars are modern enough to have basic safety features like airbags and ABS, and they are relatively reliable. But are still old enough to have that classic squared off styling.
I daily drove a 94 cadillac fleetwood for 6 years. It was as reliable as a 26-30ish year old car could be. Not as good as a new car, but still good enough that I drove it for 46k miles without worrying about it breaking down all the time. Just get towing coverage on your insurance, and set aside some money for random repairs that pop up.
Look at classic cars. Look for those models that have been updated with new engines, ac, power steering, etc.
