It had potential, but overall disappointing. The technology outdated (no visual gps), the car was way underpowered (I could have got a more powerful one for more $ of course but I wrongly assumed they wouldn't send me out in a car that couldn't make it up a hill), it broke down, and I inhaled fumes
The customer service was less than desireable. Had to wait an hour and a half to get the car, despite our booking, as there was only one person serving. They were also not very courteous at helping us understand the fine print.
The GoCar was great fun though. Easy to drive, very fun way to get around.
