360s are fun little cars but they do have their issues.
parts are quiet hard to find in Australia, anything engine related is rather simple and most things can be sourced from 240s everything else though you're buying from overseas.
classicswede is probably the best source for 360 stuff but he can be painful to deal with, sometimes he's great other times far from great.
I dailyed a 360 for about a year and never really had any major issues but lots of little issues, luckily I'm rather handy and can do the work myself and by the end pretty much everything in the car had been replaced so less things broke haha
they do have electrical gremlins, nothing major that can't be solved but things that will annoy the crap out of you everytime something new stops working, or randomly works, or works all by itself when it's not meant to haha
gearbox is known to be rather weak, I abused mine daily and it never let go but when I sold it the new owner blew the box a couple weeks later just be mindful of dumping the clutch and being to hard on it
all in all they are great little cars, super fun to drive, tail happy in the wet but handle great.
the only hard part is if something major breaks expect to jump on the net and buy something overseas and have to wait for it to arrive cause odds are you won't find it locally.
