2001 mastercraft x10

I'm getting a 2001 x10 but the boat needs 2 board racks, 2 tower speakers, tower lights, a stereo, a new swim platform, and a biminni top . how much do think this stuff would all cost. I'm getting boat for 13,900 because it doesn't have seat cushions. The seat cushions are going to cost 3800 to replace. The boat has perfect pass, a heater, perfect pass, ballast tanks, tower, hot water shower.The boat only has 230 hours on it. Do you guys think i'm getting a good deal on it. Plus do you guys think i should go for it.

please help me i'm going to test drive it on sunday and i need to know what i should do

Just depends on how fancy you want to go. You could buy some cheaper racks for $400 or swivel racks for $1500. On the tower you could do $200 dollar speakers or you could get a high end HLCD speaker for $1200. Just depends how big you want to go on everything.
