HPI has won a three-year contract with Sytner Group to provide the full range of its vehicle provenance checks which include its National Mileage Register.

Daniel Burgess, HPI automotive director, said the company had been in competition with Experian to win Sytner’s business. Trader Data Systems (TDS), closed last month by Trader Media Group, had also pitched for the contract.

He believed TDS found it difficult to compete against HPI and Experian in a tough and labour-intensive market sector.

Burgess said the Sytner contract followed its winning of one with Inchcape Retail in 2006. “We did not do it on price alone,” he said. “Sytner went with us because of the scope of the service we provide and, importantly, the flexibility we offer. We were able to adapt our systems to meet the needs of Sytner’s, rather than the other way round.”

Neither HPI nor Sytner is disclosing the value or scale of the business, nor the number of used cars the retailer sells each year. In last June’s AM100 Inchcape (£2.5 billion turnover) was listed as selling 41,031 used cars in the year to June 2006. Sytner, part of American motor retail group United Auto, was listed with a turnover of £2.2bn last June.
