Add-on profit for used car dealers — sell the upgrade, not just the car

On a thin used-car deal, the metal margin is set the day you buy the car. The margin you control is what's attached to it: alloys, tints, protection packs, tow bars, dash cams, warranties, service plans. Franchised dealers have run this play at handover for decades. Most independents leave it on the table.

Why add-ons get missed

The add-on conversation usually happens at the worst moment — paperwork time, when the buyer's guard is up and the salesperson wants the deal closed, not reopened. So it gets skipped, and a £300–£800 opportunity per unit walks out of the door.

Move the offer to the moment of excitement

Buyers are most open to extras when they're falling for the car — on your website, at 9pm, imagining it on their drive. That's when "would you like the 19-inch alloys and the privacy tint?" is a pleasure, not a pitch:

• Priced options on the listing, not a leaflet at handover.
• A running total the buyer builds themselves — self-configured extras don't feel sold, they feel chosen.
• The enquiry arrives carrying the spec, so your first reply is a quote for a bigger deal, not a fishing exercise.

Seeing it sells it

There's a reason new-car configurators show the car changing as you click. "Tinted rear glass" is a line item; your actual car with tinted glass is a decision. The same applies to wheels — show the exact alloys on the exact car and the conversation changes from price to preference.

Keep it honest (and legal)

• Out-of-stock options shown as unavailable, never hidden — misleading imagery is a consumer-law problem, not just bad manners.
• Fitting lead times on every option.
• No finance figures on configured totals unless you're FCA-authorised — your platform should enforce that automatically.

Start with five options

Don't build a catalogue; build a shortlist: one alloy upgrade, rear tint, a protection pack, a tow bar, a warranty. Price them honestly, attach them to the stock they fit, and watch which ones move. (Where this sits in the wider selling playbook.)

Where Stayloo fits

Stayloo's build-your-car configurator does exactly this: you define priced options and what they fit; buyers compose their car on the actual photos — approved previews of the alloys and tint on that vehicle — and the enquiry lands with the full priced spec.
