Wow, so many replies and ideas for which I am grateful. The novelty modified water tap protector certainly looks like it would keep out the rain.
I checked with the suppliers of my existing RCBO, taking on board the requirement that any replacement should be from the same manufacturer and they confirmed that they cannot do a like for like replacement. My charger is rated at 7.2kw but reading Mike4's comment about a 40 amp one, I found it is in stock and am minded to get one. Apart from needing to find an electrician to fit it, is there any downside in overspeccing the protection?
https://www.tradesparky.com/circuit-pro ... a-30ma-6kaUrbandreamer, I'm glad you found my review of the i3 useful. Having had the car for a few years now, I can honestly say it is a delight to use. My wife, originally sceptical, loves it. The steering is light, the turning circle is comparable to a London taxi. It's quiet and very rapid off the mark making overtaking when room is tight, a breeze as the power is instantaneous. You can get past a slower vehicle before you know it. Handling is sharp and accurate with rear wheel drive and only very occasional wheel spin if you "boot it".
Reliability has been good with just two repairs needed, top rubber mounts on the front springs were worn and got replaced. The UJ on the steering column is worn so booked in for replacement on Monday. Annual mileage is about 6000 and the car has covered about 28k miles.
Downsides are few, the ride is firm but acceptable to me. Those used to softly sprung cars might find it takes time to get used to. Range is another one. I have the Rex model which uses a small BMW motor bike engine running on Petrol to charge the battery if it runs out of electrical power. Combined range is about 180 miles before you need to add more petrol or visit a charging station. Newer models are all electric but with a bigger battery pack so, I think the range is similar but no back up as with the Rex version. Last summer we travelled to a holiday cottage at the limit of the range. The petrol motor fired up when we ran low on charge and we arrived at our destination where there was a charger available. I took the precaution of stowing a couple of extra petrol cans just in case. I wouldn't want to push far beyond the 180 miles limit though unless charging stations could reliably be found.
The car is great around town and has become our "shopping trolley". My new Octopus tariff allows me to charge overnight at just 9p per kWh so a typical charge would result in the equivalent of 3p per mile. For my sins, I have owned a beautiful E93 BMW M3 convertible since 2010 which has a V8 engine costing approx 30p per mile. It's exhilarating to drive if you can find a road without pesky speed cameras but I think I'm getting too long in the tooth for it so plan to sell it and buy another EV with a far bigger range.
Good luck in finding an i3 "goodun"
