Hi Tom, welcome along.
There is no joining fee or subscription costs, but as the site is run completely on donations, any contributions are welcome. This site has the potential to save you a lot of money on maintainance and parts costs.
How to donate to FTO-IrelandRe: the power issue, the standard battery is quite small, and it's possible to upgrade to a larger one (I fitted one from a Lexus 220 diesel in mine no problem)
Feel free to post up some pictures of the car, we're always interested in new members and their cars.
