I was going to ask you the same question haha. Never needed one as have always had access to a MIG and Oxy. I am thinking of just getting a cheap arc welder - will do my needs fine. But then, like you, I think should I get a mig because of the potential car uses.
But then you need a gas bottle for mig, or pay more for a gasless mig (never used one). I reckon 'stick' (pun intended) with an arc welder
I won't get one just yet though - I just 'invested' in a Ryobi one+ 18v Impact wrench - most expensive tool I have ever bought (needed batteries)
