Contour Enthusiasts Group Archives Forums General General bad clutch or transmision?

I'm thinking about getting a 1985 toyota supra as a beater car. the guy selling it says it needs a clutch. it started on the first try, the moter seems good for 150,000 miles. When i put it in gear i get nothing, no noise at all, no grinding and no movement. if it is just the clutch i'll buy it this weekend for only $300. carparts.com has a clutch kit for about $150. i just want to be sure it's the clutch and not a bigger problem like the transmision. any advice would be great, thanks.
