Dilemma:keep 35D or trade?

[3BEP6]

Car had vibration at idle, checked the motor mounts-seemed worn, replaced both. Problem persisted, changed the dampener with belts and tentioner. Long story on the injectors but tried flow testing and getting refurbished but we're no good, ended up buying all new just not to chance anymore. Valve cover was chasing a smoking issue. Starter failed. Control arms were worn/on the way. Vacuum lines since was replacing valve cover anyway. Transmission had a delayed 1/2 shift which was resolved with service. Thermostat and water pump are preventative since belts were off. Glow plugs unit preventative since manifold was out.

Today I also replaced oil, transfer case fluid, rear differential oil and heater valve lol.

P.S. I can't make up my mind basically as 35D still financed for a bit and getting a new car will increase the payment as well as insurance. Thank you for your insights!
