Should I buy? No Bench

[GravityHitz]

hi, i was wondering if anyone could help me out with this litte dilemma i'm having.

i saw an ad in the autotrader for this car:

Year: 1991

Model: 240SX
Model Detail: SE
Price: $3,400
Mileage: 169,000 km
Date: 5/4/03
Ad Type: Private
Comment: Super Hicas 4WS 5 spd., fully loaded, sun roof, new jet black paint job, new clutch, new all around brake system, new exhaust system, runs great, one owner, 169,000 km., $3,400. obo.

the only problem with the car is the back seat was torn, so the guy decided to rip it out and discard it. he also sold the radio from the car, but thats not a big deal. the thing is, the car looks great and the new paint is really good, but im afraid of how much a new back bench seat would cost me...if i could even find one.
I live in the toronto area, so i was wondering if anyone around there would have any idea where to find one cheap/free, or if anyone else had any suggestions. considering it has new brakes, exhaust and clutch, and a good interior other than the seats..does anyone know if this is good value or not? also, is there anything that i should pay specific attention to considering the info?

thanks in advance to anyone who can help me out.
