Just wondering if this is a decent price

[2jzgte]

Ok i have an 87 supra with a 7mge 5spd with a rod knock that i rently picked up for $600. i also picked up a 2jz-ge (non-vvti) from an is300 for $600 (I have alot of plans for this motor). Anyways I know a guy thats willing to sell me an r154 trans, driveshaft, and rear diff for $500 he claims that he bought his 88 supra with a blown turbo and is too frustrated to fix so he's parting it out. $500 seems to me like a decent price but what things should i look for when checking it out? Thanks
