Rm125 engine parts

So my dad and I are good friends with a local dealer and he was telling us he had a 2002 or 2003 i believe but not 100 percent sure rm125 engine he needs sold. A kid brought it in needing a top and bottom rebuild they rebuilt the bottom for him all brand new parts and he got the bill couldnt afford it. they said come back and pay us and you get your engine well it been 5 months so they have a complete brand new bottom end as well as a top end too needing a new piston and rings. he wants to sell it and get at least some of his money back. He always wants me to buy it but i dont build Suzukis so if your interested let me know and I can get in touch with him.
