Published in English •
Summary
- March and September: New number plates mean more part-exchanges flooding the market.
- December/January: Sales slow down, dealers are more flexible on price.
- End of month/quarter: Salespeople need to hit targets - more room for negotiation.
- Avoid spring: Demand peaks after tax refunds and before summer holidays.
Timing your purchase right can save you hundreds or even thousands on a used car. The market has predictable patterns if you know what to look for.
This guide reveals the best times to buy and when to avoid.
March and September: New Reg Plate Months
The UK changes number plates twice a year:
- March: New plate (e.g., 25 in March 2025)
- September: New plate (e.g., 75 in September 2025)
Why This Matters for Used Cars
When new cars hit the road, people trade in their old ones. This creates a flood of part-exchange vehicles entering the used market.
- More supply = downward pressure on prices
- Dealers need to shift stock quickly
- More choice for buyers
The best window is typically late March/early April and late September/early October when trade-ins have been processed.
December and January: Quiet Season
Car sales traditionally slow in winter:
- People are focused on Christmas spending
- Cold, dark nights don't encourage car shopping
- Dealers have year-end targets to meet
Advantage for Buyers
- Less competition from other buyers
- Dealers more willing to negotiate
- Pressure to clear stock before year-end
- January sales can offer genuine discounts
If you can brave the cold for viewings, December and January offer real bargains.
End of Month and End of Quarter
Car salespeople typically work on monthly and quarterly targets. As the end of a period approaches:
- They may be short of their target
- One more sale could trigger a bonus
- More flexibility on price
The last week of any month is a good time to negotiate. End of quarter (March, June, September, December) is even better.
Tip: Go in knowing what you want and be ready to close the deal. Salespeople will flex on price for a quick sale at month-end.
When to Avoid Buying
Spring (April-May)
- Tax refunds boost buyer budgets
- Better weather encourages car shopping
- Demand is high, prices rise
Summer Holidays (July-August)
- Families shopping for holiday transport
- Convertibles and sporty cars in high demand
- Dealers less willing to discount
Early September
- Before the trade-ins have hit the forecourt
- Wait a few weeks for better selection
Seasonal Vehicle Demand
Certain cars are in higher demand at different times:
| Vehicle Type | Peak Demand | Best Time to Buy |
|---|---|---|
| Convertibles | Spring/Summer | Autumn/Winter |
| 4x4s and SUVs | Autumn/Winter | Spring/Summer |
| Family cars | Before school holidays | September after holidays |
| Small city cars | January (new year resolutions) | November/December |
Buy against the trend for better prices.
Economic Factors
Beyond seasonal patterns, wider factors affect prices:
- Fuel prices: High fuel costs increase demand for economical cars
- Interest rates: Higher rates reduce finance affordability
- Economic uncertainty: Slows big purchases, prices may soften
- New car supply issues: Shortages push buyers to used market
Best Day of the Week
Weekdays are generally better than weekends:
- Fewer customers means more attention from salespeople
- Less pressure to rush your decision
- Better chance of a test drive
Tuesday to Thursday are typically the quietest days on forecourts.
Private Sales vs Dealers
Private sellers don't have targets, so timing matters less. However:
- End of month sellers may need money for bills
- Cars listed for a long time may have motivated sellers
- Sellers going on holiday may want a quick sale

Negotiating Tips
- Research market value: Know what the car is worth before you go
- Be ready to walk away: The best negotiating tool
- Mention competitors: "I've seen a similar one at X for less"
- Ask for extras: Mats, full tank, warranty extension
- Visit at month-end: Maximum leverage

Common Questions
Is January a good time to buy a used car?
Yes. Demand is low after Christmas, and dealers want to start the year with sales. You can find good deals.
Should I wait for the new plates in March?
If you can wait, yes. The influx of part-exchanges typically improves selection and may push prices down slightly.
Does time of day matter?
Slightly. Going early gives you more time and attention. Going near closing time can work if the dealer wants to end the day with a sale.
Final Thoughts
Timing isn't everything - the right car at a fair price is more important than waiting for the "perfect" moment. But if you have flexibility, buying in quieter periods or at month-end can definitely save you money.
Combine good timing with solid research and negotiation skills for the best deal.
