We replaced a 1992 EZ GO electric (Upgraded motor) that went all of 15 miles on a charge with a 2010 EZ GO AC electric. After a year we still are impressed with its performance. We have a spedo/Odometer on it and have gone 30 miles a few times before recharging with the meter showing only a little below 1/2 charge. Top speed is a consistent 22 MPH. And as you noticed pick-up is great. I don't think I'd try to even get close to 60 miles on a charge so who knows if their claim is reasonable. ( For all we know the guy who rated the EZ Go is the retired Federal DOT worker who assigned the milage claims to all the new cars. (down hill, with a tailwind, motor off, with a 60 pound driver, never exceeding 10 mph, no air, no power anything, etc.)
We've had no problems so far (2800 miles), but it seems that some of the 2009's have some real issues. From prior posts its hard to tell if the problems are serious or if the dealer is incompetent at supplying a fix.
Our neighbor has a 2009 , beats the heck out of it, and so far it has not given him any problems. ( 6000 miles on his spedo.)
We also have a gas Club Car which I wouldn't give up. MY wife had to have the electric, but so far I'm impressed with the thing and it has become the main cart in use.
One neat feature of the EZ Go is the automatic "parking" brake lock. Orginally I didn't think much of it during the sales pitch, but I sure miss a feature like that on my Club Car.
