i'm moving to rural maine from LA and i want a truck but don't want a new loan, worth it to lift my gray subie on the left?

i know getting a new vehicle is smarter but my impreza only has 59k miles on it so wondering if investing a few grand on a lift and new wheels would be worth it or the MPG hit and stuff makes it pointless. I want a truck but don't really want to have a new loan since this cars paid off. I have a friend who has lifted trucks so think we could do it on our own just buying the parts...
