I was referred to Ian by a coworker, and I could not be more happy with the results! He replied in a timely manner, he was polite, he really dug deep into finding what I needed in a car, what would work best for how much I travel & kept my budget in mind. When I said no to something, he never once pushed. He was honest about how everything worked. I would 10000000% recommend him to anyone I know who is in the search for a car that works for them! Thank you again, Ian!!! More
