I was introduced to this long-established family-run business by a friend who's bought some 8 cars from them over the course of many years. What a RELIEF to deal with these no-pressure folks who have a casual, helpful approach to working with you.
I considered several vehicles, and checking values from consumer information, 9th Ave's prices were at or below fair market estimates on all of them. The car I settled on was immaculate with low mileage ("Kilometre-age"?) at a very fair price. The deal itself was straight forward, with none of the haggling, none of the "stealership" sales tactics (e.g., "Write your offer on this slip of paper, and wait here 20 minutes while I advocate for you with my sales manager...")
As to my trade-in? They advised me not to! Told me my old car would be an easy private sale in this market (Suby WRX), and I could probably get $4k more for it with little time or trouble.
I'll be going back to 9th Ave for future cars, have recommended them to friends already, and I recommend you consider them when buying a used vehicle.
