New 163BHP Grand Cali 600

[David M]

Just enquiring on how anyone is getting on with the new 163hp engine compared with the older 24 model with 177. I am looking to buy and not sure if I want the new 25 model,( minus the solar and or wiring loom) or find a nearly new 24 model with perhaps a solar panel and if not at least the wiring for the solar to the roof aerial.
Please advise your thoughts and if anyone with a new model has had any gripes with the new engine and interior electronics?
thanks
