I’m also fortunate to be less than a year in.
I have got my last three cars from the same dealer, travelling over 100 miles for this one having moved away.
He is proactive in trying to “sell” to Motability customers and has always offered me a fair bit off the AP.
He was open about the fact that whilst not making as much on each individual car as he would on a private sale, his manager encouraged Motability sales as they counted towards their sales figures and had an impact on both monthly and annual sales meaning any bonus was obtained in that way.
