Dixon Motors has teamed up with the AA to create the Dixon Accident Support Service.
Dixon has calculated it takes an average 15 phone calls and letters to settle an insurance claim. Its offering aims to reduce that to one call to DASS, with the car collected and delivered to a Dixon Motor Clinic, a replacement vehicle provided with all liaison taken car of between the insurer.
Every Dixon Guarantee or Dixon Assist customer - about 50,000 people - will be eligible to sign up to DASS.
The AA would carry out the roadside recovery and where necessary take the car to an Dixon repair centre.
Dixon finance and insurance manager David Storm said: "We hope that Dixon customers never find themselves in an accident situation but if they are, they can be sure they'll receive fast, professional and reassuring help."
DASS was launched this week. It is free to Dixon customers.
