Doubt if reparing a Nissan 350Z

[Peldrigal]

My 2006 350Z revup roadster is in need of a lot of work. The engine has a terrible rattle, apparently for running oil starved, and misfire, which probably means a new engine, it needs a new clutch too. It's on about 95k miles, and I was thinking to sell it regardless, because my family is about to grow and I am driving very little lately.

I have been quoted around 3.5k in parts and labor, and I am wondering if I should repair it and sell it in good nick, sell it with all its faults, or scrap it.

Any opinions?
