The fit might be important - there is
some adjust ability in that BCD but it needs to start around the right size for you as the component pieces can't easily be swapped. It's an XL so you can check the fit range here:
SCUBAPRO - BC SIZING INFO
A Scubapro MK25/S600 is an industry standard, solid higher end regulator. They're basically the top of Scubapro line and that one is basically unchanged from a new one. New that particular model is $729.
Scubapro MK25/S600 Regulator 12.971.040
Scubapro is also a higher end brand than Mares IMO.
I'll frankly admit that I don't like Mares - they seem to develop new gimmicks that have no useful function. IMO they use too much plastic. There's a recent thread here about a woman who had both sides of her Mares lumbar tank support snap before she reached 100 dives her first year. It's plastic...
Mares looks flashy but I question some of their underlying principles. AirTrim seems like a good idea on paper until you realize that in order to make it work there's a system of valves, o-rings, pneumatic lines and special dump valves needed. All proprietary and impossible to get parts if you're not near a Mares dealer. If the Hybrid you're looking at has it - I personally wouldn't. Even Mares seems conflicted, a few years ago they had three or four models listed on their website - now there's just the one on the Hybrid.
I know someone who dives a Knighthawk - has for the past decade or so. It still looks/works fine. Configured with the AIR2 that's $750 retail new today.

Somehow the seller got hold of a console that's 20 years older than the rest of his gear. There's nothing wrong with it and he's upgraded the gauges since they don't come mixed like that. More than likely they can be popped out and put in a more modern console - or you can buy the equivalent new for around $200. Have it serviced so you know that it's reading both the right tank pressure and also accurate depth. I'd be slightly concerned if the hose was original but that can be changed also.
Since you mentioned only the one local dealer nearby - check them on ScubaPro's dealer list here:

Any one can probably service the BC if needed. The regs should/need to be done at a ScubaPro dealer since they'll have access to parts etc. and have factory trained techs. It's not an overly difficult regulator to service but it is more complex than a $200 Mares Rover. Something you kind of want to be done right...
Since you're not the original owner - service will include parts costs as well as labor. Plan on $40-60 a stage (1st, 2nd, Air2) and they should include the gauge spool/o-rings free. If you don't have a ScubaPro dealer nearby - Airtech in NC can service it.

If you go look at it, first thing inflate the BC fully and listen/watch for leaks. Maybe dunk it in the tub also if the seller doesn't mind. Try everything, he should be storing the tanks with at least some air in them.
I would not bother with used aluminum tanks. You're going to spend $40-50 for the hydro and VIP to get them going.. assuming they pass. You can find brand new al80's at LDS sales for around $100 around where I live. Most dive boats provide tanks for the divers anyway.
I agree...
What are they asking for it all? It's all significantly better than average gear - I could actually be diving the
exact same thing myself now (except I wanted the Titanium Mk25/S600) except I chose Zeagle/Atomic at the last minute. I can afford anything I want so I based the decision on the quality of the gear.
Like Kelemvor - I'm a 1/2 off for used gear guy since that's what it dropped to when the buyer got it wet the first time. That's about as much as the store he bought it from would give him - probably less.
