Zoes are fine, so long as they have fast charge and are the last generation (52kwhr)
The software is pretty shit. Lagging and annoying. But apple/android play stops that.
As a car its smooth, quiet, and fast if you need to be. The only annoyance driving wise is that it doesn't have adaptive cruise control, and the reverse/drive/neutral switch always returns to the middle, so you can't tell what mode its set to without looking at it
It depends. Zoés come in many flavours, with different sizes of battery (52kWh is the best, the same size as current Renault models R4 and R5), rented or bought (don't buy a Zoé with a rental battery!!!), and the CCS2 port is in option (no CCS-2 effectively means no day trip longer than full range, unless you have the 22kW AC option, but still... you'll need to find a 22 kW charger en route, not that easy).
Battery management on Zoés is fine ; it doesn't have the overheating problem that plagues the Leaf and the VW e-Up in particular; it doesn't have the "very slow charge when cold" problem of many cheap EVs with LiFePO4 batteries, though it charges up quite slowly (10-80% in 50 minutes).
Someone I know recently bought a 135HP 52kWh Zoé without CCS-2 and 22kW AC charge for 7500€. That's a real bargain, it'sequivalent for all practical purposes (but long travel) to a brand new 30000€ R5 :)
