I'm not scared of the electrical "nightmare".. if I can fix a AH-64D then I think a vehicle that operates on only 2 axis should be a piece of cake.
The AH-64 has triple redundancy for each and every system and flies via a computer, you also can not fly it in the rain without it falling out of the sky. There was a replacement being developed that addressed these problems, but the govt killed it... your tax dollars at work.
I was always told that an S320 was still fairly simple... but since owning a 400E, I don't think I could pass up an S420.
That car can't be nearly as bad in the rust department as the thing I just sent to the scrapper. I bet someone could snag it for 1500ish.
