#2/15 Extra features are a trap
Never doubt it, a car salesman will always try to sell you extras. Bluetooth, special seats and many other features can end up being more expensive than the actual car. You have to be very aware when negotiating, since it is very common for salesmen to sneak extras into the deal. Car dealerships usually have very good offers for cars with few or no extras, be aware of this and try to avoid increasing the price unnecessarily.
