Yeah, there are those other costs
All of which except the congestion charge and road tax apply to both vehicles.
I'd still have to insure it and to service it either way.
Tyre cost is irrelevant as I've not actually needed to replace any tyres on my rust-bucket in five years, so I'd expect these to last at least that long. (The odd puncture repair job, but that'd happen to anything)
Insurance is an unknown - I'd guess insuring a brand-new vehicle to be more expensive than an older one, but that is a guess as the vehicles are in very different classes.
Servicing the Renault is not going to be cheaper - I can take an infernal combustion engine to any garage I like, while this Renault would have to go to the dealership - and probably a specific one.
That takes the cost of a simple service way, way up, so the 'simpler' Renault service may well be more expensive! (And maybe it's not even simpler?)
As to the brand-new/second hand comparison - this makes perfect sense. This vehicle would not be the first vehicle in a houehold, and it's aimed at 'greenies'. What's greener - buying a brand-new vehicle for your second 'commuter car', or buying a second-hand vehicle?
The rust-bucket is clearly greener on the manufacture argument, so the new one has to be green (which actually means cheap) enough to run to outweigh the materials cost.
However, if you're in the congestion charge zone daily, you have a good argument.
So that's the only place on Earth that'd I'd ever expect to see this vehicle.
