As usual thread being derailed with pointless comments... anyway...
Similar situation. Had my car 4 years and love it.
Probably getting a paid for work car soon, but regardless I am going Fi (picking my car up on the weekend. Woot woot!)...
My reasons are simple... I love the car, it’s handling and rwd character. A new car is much more expensive when you included insurance increases etc, plus all I really want is a little more power.
I’ve also enjoyed the process of reading, research, learning about FI, etc which adds to the overall enjoyment I guess.
Personally... I say keep the car and go FI
