Most people defer selling until the EV path feels real — then discover WBAC offered £2,000 less than Autotrader suggested. The gap between platforms is not a rounding error; it is often the difference between “affordable switch” and “wait another year”.
Nail down your EV budget and finance first. Know what you can borrow or spend before you fixate on what your current car is “worth”. The sale proceeds set your cash gap — not the other way around.
Get at least two sale routes. Instant-buy quote, part-exchange chatter, and what a private listing might fetch if you can tolerate the admin. The spread between them can fund a year of home charging.
