What year should I look at

[live2drift2live]

Hey guys, this is my 2nd post and I need some help picking what year I should look at to buying. I want to do all my research before I invest in it. I was looking at early 240s but realized that I will not have enough money to get an engine swap (I need DOHC). But, I am just trying to learn the differences between the years(besides price) and any major problems I might run into.
Thanks

You should try doing a search. You should be able to find the differences between the newer 240's and the older ones. also you should be able to find all the problems that each generation has
