GM is putting its weight behind plans to put the Cadillac brand into the minds of Britain's user-choosers.
After a faltering start under a Dutch-based importer and small UK network of dealers, GM has now brought the operation in-house, along with its Hummer and Corvette cousins.
This means that the American trio of brands will be managed in the corporate sector alongside Vauxhall, Saab and Chevrolet.
Maurice Howkins, fleet sales director at GM UK, said: "This integration is designed to make life easier for our customers under the GM umbrella.
"We have six brands and aim to be a one-stop shop as we know that people do prefer to have one point of contact when it comes to buying vehicles."
To make the Cadillac brand seem more attractive, GM has unveiled a new-for-2008 range that includes a BLS estate model.
As a special offer, buyers can upgrade from a saloon to an estate for free, while the BLS range as a whole now comes with a lengthy list of standard equipment added worth £4,000.
All models are fitted with electric leather seats, satellite navigation, Bose stereo and Bluetooth mobile phone connectivity, parking sensors and dual-zone climate control.
Prices start at £21,495.
Jonathan Nash, director in charge of Cadillac UK, said: "Business sales will be an area of focus for us with the BLS."
The two new engines - a 180bhp diesel and a 200bhp Flexpower bioethanol/petrol unit - give us an opportunity to highlight the upgraded models' attributes to the business market.
"These engines are highly competitive for CO2 and offer benefit-in-kind company car tax advantages.
"Industry response to the range has been extremely positive.
"CAP is predicting a boost for residual values because the BLS is so highly equipped as standard.
"The BLS range will be joined later this year by the CTS - a sharply-styled executive saloon powered by 2.6 and 3.8-litre V6 petrol engines.
