Yeah, her spiel about her health yesterday raised so many questions the bit about the car seemed to slip past mostly unnoticed.Her car needs work already, go figure. Timing belt issues are not necessarily an "easy fix" like she's talking about. She probably paid about $4-6K for that car and she'd going to need to put about 2K-3K into it just to keep it running over the next couple years. I'd assume that the brakes, tires, and suspension are all in need of replacement at the usual 80-100K mile mark. That is also usually the time when the water pump, serpentine belt and thermometer will need to be serviced as well.
Far from a car expert but as someone that has owned one past 100K miles that's the sort of maintenance that you can expect.
I still can't figure out what is going on. She claims she sold her last car, which she was still upside-down on. What happened to the money she owed on it? Did somebody pay it? Where did she get the money for this car? A 2016 vehicle is unlikely to already have 100K miles on it (but not impossible); 45k-60K would be considered "normal usage" assuming it was originally sold in 2015. If she has more miles on it than that, then the last owner drove the thing into the ground. KIAs are not known for reliability; I wouldn't pay much more than $2K for one with over 80k miles on it, if that. Actually, I wouldn't recommend buying a KIA at all.
She makes it sound like she bought it from a dealer, but a dealer would not let a car be sold with a check engine light on. They would fix it first. So, as usual, she is lying about multiple things in regards to her stupid car. I am happy it is giving her trouble though. It seems to me she would have been far better off keeping her old Toyota and just fixing what was wrong with it (even a rebuilt engine would probably be cheaper than buying a new used car with a check engine light on)
Fixing a timing belt usually means taking the engine out. That costs money.
