Dumb question because inquiring minds want to know... so... can't you just drive your dad's car?
That asked, dumb question two: your buick keeps breaking from what I've read of your threads, and, between your earlier trying to trade it and all the rest, you don't seem especially attached to it. Why not trade it for a craptastic but dependable rice burner like a 1990s accord or civic. They're ugly, crappy cars inside and out, but, you can rig them to keep running past the 300k mile mark like I did for my fiance.... we parked hers at 364k, still ran/drove even with broken abs pump, busted half shaft, blown struts/shocks, ps leaked almost a dollar tree bottle of fluid a day and groaned, trans slow as heck due to being worn out, no ac, engine bucked on acceleration due to oil fouling the plugs at dist o ring, air bag modules failed, pw failed, do defrost or defog, just a $1 mini squeegee to use while driving, radio permanently blowing fuses... but even it still ran and moved a to b when we ordered the brand new mustang.
If your goal is what you say you don't need a 32 year old buick. You need a dependable economy grocery getter.
