The 1989 240's use the single overhead cam version of the KA motor. These motors have a potentially expensive failure waiting to happen if none of the previous owners swapped in new timing chain guides that are backed with metal. This isn't something you can tell from the outside of the motor either. If she's the original owner, ask her what work has been done on the motor. Ask her specifically about the timing chain. If she claims to have had it done, see if she has invoices and/or knows where the work was done. You may want to follow up with the shop, especially if she doesn't have any invoices.
Personally, I would have reservations about the single overhead cam KA's. I'd probably look for a 91+ 240sx for that reason.
As far as using this car for a child with a safety seat, I'd maybe think about finding a car that you can mount the seat in the center of the rear seat for. It generally offers the best protection for your child in almost any kind of impact. And trying to access the back seat is a chore in these cars. I'll always have reservations about putting a safety seat or a small child in the front seat. Even without airbags. I'm not going to tell you that you have to buy a mom car, but the 240 is not a very child friendly car.
