Well yes and no. A poor charge rate on a small battery means it will probably charge, from a SoC perspective, as fast as a bigger vehicle with a faster charge rate…but it’s adding effective range more slowly - and considering you need to stop more frequently, it compounds the disadvantage.
Whether it’s true or not isn’t really important. Someone working for a specific brand having access to a vehicle from that brand is common, so it doesn’t really say anything about purchase intention or experience.
A random person you meet has the vehicle and tells you that it’s great/awful is probably more useful than anything the people trying to sell you a vehicle will tell you.
