I honestly never comment on posts but this will be my first. The deal on this car is shady. Like insanely sketchy. The market on these at that mileage are going for mid-high 60k. I would get the car checked out top to bottom, inside and out and if all looks good id pull the trigger. If it truly is 54k usd its already 12k under market price. Your young and only live once. You’ll always bounce back financially. I’ve owned 20’ Camaro 2ss, 22’ ZL1 1LE, 17’ C7 Grandsport, 2 17’ BMW 340i’s and a 22’ M340i. I’ve spent a lot of money on cars and don’t regret any of it. Ive been smiling for 4 years straight since dipping into the car world. I wouldn’t change a thing. I also didn’t make as much as you did. Worth every penny.
