to buy or not to buy?

I found a 91 z24 cavalier that is in great condition. it is a 5 speed manual transmission with many options. 2nd owner says it runs great and has never had any problems. I have heard that this year cavalier has many problems and with 159000 miles idk if i should buy it or not. $1800? keep in mind that this is for a 16 year old boy that WANTS a car. Have you heard of any problems that occur often in these cars and do you think it is a good buy?

You could probably find a better car with less mile for 1800

got any suggestions?
