I haven't used the Mako, so I can't answer all of your questions, but here is what I think...

If it shows 120 minutes as the maximum time, I would scale that back by 10 to 15% to estimate what you will get in reality. 

All batteries have to be replaced eventually and can be damaged if the user doesn't take care of them.  Things like overcharging, deep discharging or leaving them in a discharged state for too long can shorten the life of any battery.  While a certain used scooter may look nice physically, it could have a weakened battery so that is another problem that you might run into.  It's probably a safe assumption that the battery in any used scooter is not at 100% capacity any more, so you should factor that into your cost analysis.  The battery may still be good, but it won't be as good as a brand new battery.  If the used scooters you are looking at are 5 years old or more, the batteries are certainly not at 100%, especially if they are lead acid batteries.  Lead acid batteries are cheap, but they don't last long.

Buying anything used is a gamble.  Maybe you get a good one, maybe not.  Sometimes you get a great deal and sometimes you get hosed.  At least with a new one, you would expect it to be good and there is a warranty. 

I am very particular (some say I am too particular) about equipment and how it is maintained.  I almost never buy anything used unless I know that the seller took very good care of it. 

Keep us posted on what your final decision is and how it works out.
