Overall used car values fell 2.2% in March.
This was caused by a fall in retail and trade demand due to the Covid-19 crisis, according to cap hpi.
It was a month of two-halves with trade values tracking at a -0.3% from the previous month on Friday 13 March.
However, there was a dramatic effect on used car prices from Monday 16 March as demand fell.
The number of cars sold on Friday 20 March was 23% lower than on Friday 6 March and 19% lower than on Friday 13 March.
The total cumulative Live movement during March, leading to April’s monthly values, was an average drop of 2.2% (-£275) at the three-year, 60,000-mile point, the majority of which happened in the final 10-days of valuing.
For newer used cars, the drop was 1.8% (-£425) at the one-year, 20,000-mile point.
Derren Martin, head of valuations UK at cap hpi said: “As you would expect, all of the main sectors have been affected by this decrease in values.
“Rest assured, the movements that have been made in March have been reflective and not an over-reaction to feedback or industry ‘noise’.
“We are aware of reductions by some online car purchasing sites and some remarketers, but our adjustments have been purely as a result of used car transactional data.”
Cap hpi expects that in the short-term both used and new car sold volumes will reduce dramatically, as the industry has already witnessed in the immediate aftermath of the country lockdown.
He added: “We will be analysing the data as always, but not adjusting used values while there is insufficient data. In effect, if vehicles are not selling in quantities anywhere close to normal, we will not be adjusting.
“No overall market adjustments will be made based on historical data or opinion; outliers and unrepresentative sample sizes will not be reflected. We will be closely tracking retail volumes and prices, but not adjusting any trade values from these.
“We feel this is the sensible approach in these unprecedented times – we always have a duty to reflect the market, but at present, there is not enough of a market to do so accurately.”
