Enjoyed Kelly and Rob Ash - Mr Ash did a nice job explaining the features of the carf Everyone was nice and low pressure. Requiring 25 words in this review is the worst part of the whole experience lol...

Stellar job by Mr Breese, Archie and Mr Power, as well as the the shuttle driver. Overall experience was top notch. I've recently been discharged from a bankruptcy and everyone worked diligently and quickly to get me approved to for a vehicle of my choice and I am never been happier. I highly recommend this team to everyone.
