All of work on commission in a sense. Work hard, get paid and maybe a raise. Goof off, get fired!I always worked hard and I would see my paychecks fluctuate according to the whims of customers. I will not allow whims to determine my income. This is a problem specific to Carmax. At a regular dealership I had a lot more control over my income but at carmax...with their automated "Ups" system, the selling process was more like a lottery draw. Would you get:1) Customers who want to see "what their car is worth" via Carmax's much-advertised free appraisals. They have no intention of buying or selling anything. 2) Customers who want to "lower their payments" because they cannot afford their 2005 GMC Yukon Denali XL and want something closer to $300 a month.3) "The BMW Guy"...usually a young professional (w/ girlfriend in tow) who thinks he has more money than he really does and wants to do nothing but test drive BMW/Acuras/Lexus' all day without having the means to buy anything. Usually wearing nice clothes that he put on his maxed-out Banana Republic credit card.4) Customer who has champagne tastes on a beer budget.5) Customer who is extremely and unreasonably picky about options and color and does not understand that there aren't Nogaro Blue Audi S4's on every dealer lot.6) people with bad credit and no money down7) A customer who, if they find the right car at the right price, is willing to buy a car.So when I sign in to the front desk at Carmax, I am at the mercy at whatever customer walks in the door. There is a very slim chance I will get customer #7 above. If Customer #7 happened to call or email Carmax beforehand and I sell them a car, whomever they spoke to in email or over telephone gets HALF my commission.When undesirable customer 1-6 comes through the door, Carmax policy dictates I am assigned to that customer and cannot leave them until they leave the store's property. I am stuck with the losers. At a regular dealership, I can "broom them" and find a better prospect.The only reason I worked at Carmax is they allowed part-time sales. At a regular dealership you don't see people who are selling 16 cars one month and 4 the next. Sure, there is some fluctuation, but not that much. At Carmax, huge fluctuations are the norm...and these fluctuations are despite the salesperson's best efforts.For whatever it is worth... , Bought from Carmax or thinking about it? Ask questions and share your experience here!, Hi folks: Is it better to buy a used car from CARMAX or a dealership - from all standpoints - price, quality, reliability etc..
