The Grand Marquis is the definition of unkillable with cheap maintenance
Except for Subaru lol
Modern Subarus are very reliable
They are but at the same time im not a fan of any car that makes it easier to go to the stealership than work on your own vehicle
They aren’t that unreliable they just aren’t mod friendly
The pre-2015 n/a 4cyl is even easier to work on, the headgaskets do start to leak but they’re super easy to replace
