Just designing such critical robotic equipment is going to cost an insane amount of funds.
It is indeed a challenging proposition, but I feel that your statement (as much money as the development of such rovers
would cost) is somewhat unjustified. The only point to work off of is scientific rovers developed by NASA, which are practically one-offs, produced in an organisation with a specific design culture and that contain numerous (and quite pricey) scientific instruments.
Then you have to have a power system remotely landed and managed.
It is not impossible, just an unknown. It isn't like power generating hardware has not been deployed in space before, it just hasn't been done in this specific environment.
EVA suits (Nope Orlans from russia will not work)
I don't know if anyone is seriously suggesting using Orlan as a Mars surface suit, at least not in the west (they sound bad enough to use in microgravity). Not even Mars One proposes it (they just vaguely state that Paragon Space Systems can "produce these Mars suits" :facepalm

.
People
are working on suit technologies with Mars in mind, it's just that the field is still fairly experimental.
Things in this area are improving- MRO can transmit at 6 megabits/second, and LRO at 100 megabits/second. The internet that I use to view O-F isn't a third as fast as MRO.
If it was so cheap and easy to get to the moon to stay we would have done it decades ago.
The reason people never went to the Moon to stay there decades ago isn't because it's impossibly expensive and difficult, but because the major space agencies of the time decided to take different routes of development- NASA by developing STS (which was intended to eventually lead to space infrastructure and a Moon base, which obviously never materialised) and the USSR by focusing on space stations and later, trying to copy the US.
