    Hello, I got my prius at 17 years old from my late mother who bought it new and did routine oil changes at a good mechanic.
    Now it needs a new Hybrid battery.
    I'm not well educated on mechanics/ cars and wondering what your opinion is on getting the new battery? It would cost about $3500 at my local mechanic total.

    Here is the thing:
    If I sell that and my 2000 Sienna, I could MAYBE get what/ Like $4-6000 total? My Sienna has been given Hospice orders... those repairs would cost $1500 but I'm also wondering if that would be a better option. Or that I would keep both because my daughter still needs transportation to college in town.

    If I buy a newer car for about $8-10,000 it will probably have issues right away because people sell their cars when they need repairs. I have gotten my last 3 cars when they were 17 years old. I needed to do repairs. BUT the insurance is cheap, registration is cheaper.
    I am weighing doing this repair vs buying a newer car that I will likely need to put $2000 into right away anyway and I don't know its maintenance history.
    I am a single woman trying to save for retirement and don't have extra to buy a $25000 car and pay that high insurance rate.
    What do you think?
    (yes, I'm sort of decided on going ahead, but I'm worried I'm making the wrong decision)
    Thanks

    What's a hospice decision on the sienna van ? Sienna year 01 to 03 yes you want to keep that series van . Sounds like it's time for timing belt etc. the Prius . You should be able to beat 3500. Putting in HV battery should be 1.5 hrs shop time at 135 hrly . That ain't much . but HV battery online thru Toyoda to get max discount . There is done debacle over selling batteries to regular humans you may have to push thru that . The internet will tell ya how usually call dealership setup acct . Send yer son or boy friend over to pick up in a blue work shirt . That sort of shiet . just have to act like one knows what's going on. I know more about what's going on at toyoda dealer than the office staff over they're. He he
