The price point and packages included influence the sale of the vehicle. If we start with the price point, we know that people look for a great car at the best price. Through my experience selling expensive cars can become a headache because this is where you can earn or either you can loose a lot.
When the buyer wants to spend more then $15,000 on a car, they really want the car to be perfect no matter if the car is 6-8 years old. So what they do is take it to a shop for inspection:
Do you really think the inspection results will be positive? Oh no! They always find something to replace on your car. For example when I took my formal ML350 to the shop they said I have to replace the Air pump, the battery, the timing belt and there are oil licks so they estimated the expenses at $4000. My advise is don't go to a shop when the buyer asks you to inspect the car.
When buying an expensive car you want to think about the resale value, as after a year or two you might want a bigger or a smaller car and you want to sell the one that you just bought. It is important to read reviews, to check Carfax and what will really help you to keep the price up is the packages included on your car. You want the car to be loaded, even if you don't use the Navigation or other features, they will keep the value up! Especially if we talk about expensive cars, spending more then $15-20k and not having sensors or heated seats will devalue your vehicle quiet a bit!
The cars into the price range of $5000-12,000 sell the most and it is easier to make the sale and earn money on them, why? Because there are more people on the market for affordable cars and for some reason $10,000 is easier to spend then $20,000.
The cars that lead the streets of your town are the once that sell. We talk about Toyota Camry, BMW 3 series, Honda Civic and others. The weekend cars usually go out last. But there are still customers for all of them.
