Aircon re-gas - how often?
When I bought my GT4 last October the aircon was freezing - really cold. I didn't use the car a lot over the winter and when I did, I didn't bother using the aircon - too cold anyway and it saps power from the engine.
Is the aircon on a Ferrari (esp. of this age) anything special or can it be re-gassed at the garage that re-gassed my other cars (Merc, BMW, VW)?
Is it normal for the gas to leak out in this space of time i.e. Oct - Mar? Why does the gas leak out anyway? I guess these problems can get expensive?
