Distinguishing repairs from improvements. Purdy Company acquired two used trucks from Foster Company. Although the trucks were not identical, they both cost $15,000. Purdy knew when it negotiated the purchase price that the first truck required extensive engine repair, estimated to cost $4,000. The repair was made the week after acquisition and actually cost $4,200.

The firm made this repair, costing $4,200, during the week after acquisition.
