the only thing I would be concerned about on Moms car would be the tranny... altho the engines are good for 300K the trannies like to quit at around 125/150... if it was dealer serviced then keep it that way,,,if the tranny was not serviced,,,DON'T sevice it,,,it is the kiss of death...

Obviously money is not an object,,,but if it was a munual it more cost effective...
