Our easy-to-use system helps you collate accurate information for a realistic trade price, minimising risk and maximising retail opportunities.


Accurate part-exchange valuations rely on clear vehicle images, and our Image Capture tool simplifies the process for you. We provide up to 20 high-quality digital images to show each vehicle type, specification, colour and trim, plus evidence of any damage or wear and tear, meaning greater visibility and an easy, realistic valuation process.


Our team of valuation specialists researches multiple routes to market, adjusting prices every week to ensure the most up to date, accurate valuations. We support dealers seven days a week, valuing anything within 15 minutes.


Our market-leading, 98% valuation accuracy allows your team to offer the most competitive and profitable part-exchange prices, and negotiate sales with total confidence. We think it’s the smartest and most essential used-car valuation service on the market, and our dealers agree.


Identify part-exchanges with retail appeal, and push them straight to the forecourt to optimise your prices and stay competitive.

We’ll reconcile the balance and return the profits to you after the sale, allowing you to maximise your cash flow and free up space on your forecourt for the cars you really want to sell.


We’re so confident in the accuracy of our valuations that we offer optional upfront funding before the vehicle is offered for sale, freeing up cash flow to support your business.

We can arrange a BACS cash advance into your bank account the day after the vehicle arrives onsite at one of our auction centres, and after the vehicle is sold, we’ll settle up any difference between the valuation and final auction sale price.
