Would I buy a 240SX again? Yes. Would I buy my 240SX again? No.
My particular 240SX has a lot of issues. The rear subframe bushings are shot, it needs a new clutch, new suspension, rust repair, paint job and could also use some other touches.
When I looked at it and test drove it, it seemed to drive just fine (and to be fair, it still does despite all of the things listed above) it looked OK, and the price was right.
The lesson I learned: no matter how good a (used) car seems, have a checklist of things to look at carefully and also have it checked out by a garage that you trust. Knowing these things before-hand, I would have kept looking for another car.
But what's done is done, and nothing here is irreparable. I just have to spend some money on it.
