I bought a Zoe signature nav r110 ze40 two years ago for £15k. I tend to change every two years so thought I'd start looking around. The car has low mileage 18k and is immaculate. The best price I've been offered offered on px is £5500!!! How on earth has it dropped £9500 in two years?? Has anybody else encountered this or is it just me? Also, when dealers search the database, my car doesn't appear. Could this be because of the battery lease or some other error?
