What do you guys think about mitsubishi io 2.0?

my wife and i are thinking about getting Mitsubishi io 2.0? we want to buy a used one to avoid the initial depreciation of a new car rolling out of a dealership. we have been going on SUM to look at whats out there.

  1. what do you guys think about SUM dealerships and buying used cars from them? any advises would be appreciated!
  2. what do you guys about about a 2012 and up mitsubishi io? our budget is around 650k, seems like the price for a 2012 io varies quite abit, some 1.8 prices the some as 2.0
