Well, the most I can get for my 6-month old Trophy with 3,800 miles is £22,000 with one of the online purchasing supermarkets, or about £20,500 trade in at MG. That's a third of its price in just half a year. Doesn't really matter to me as my wife loves driving it and will now only ever drive an EV. Hard to say at the 7 to 8 year point as the battery warranties start to expire and only time will tell the condition of the batteries and, more importantly, the sentiment of the marketplace for older EV's against whatever are the newer offerings at the time. We just enjoy the car now and do not regret the purchase for a single minute.
