Need Some Advice From My Subie Fam

So, here's the deal, friends. For the last 17 years, I've had an 02 Impreza as my daily driver. I call her Sadie. We've been through a lot together. She's seen some stuff.

Sadie just had *something* go wrong in the engine. I'm not sure what exactly yet. I went to pass someone on the highway, and when pulling back into my lane, it started making a loud clacking noise and the oil pressure light came on. Still runs. Still seems to have plenty of power, but the sound is persistent.

She's a 21 year old car and needs bodywork, fresh paint, and new suspension. But I love this car. I estimate probably $8-12K to get everything fixed up and good as new. I don't have the cash on hand since I just paid off a bunch of stuff, so a loan will be in order.

My head tells me that it's time to let Sadie go and get a new Subie. I can probably buy a new Outback for a similar monthly payment or possibly lease a Solterra for a fair bit more.

I just don't know which route to go!
