Came in to help my nephew find a low cost lease to get him through college. Without asking for our budget, salesman took up to a car and said this would fit our budget...? I asked salesman for a listing of the lease specials and incentives going on and he told me he couldn't until after we decide on a vehicle. How can we decide then when the boy has a strict budget that you didn't ask me for? You could show him the most expensive car in the showroom and if he can't afford it, we would be wasting time. The salesman got really agitated and started acting like a jerk. The manager came up (knowing me from a purchase I made) and ran the numbers and found a car that they could meet the budget; it wasn't the car he was showing us... The salesman was then asked to bring the car up to show us. 15 minutes later no car and no salesman; we left. Note: When we have bought a car here before we were always shown the deals of the week. Maybe it was because we knew before hand and asked about but still. If the buyer asks for this list why not produce!?
