Ok well I am not going to say any of you are wrong. Now cars may lose some in evaporation and steam, but in a sealed pressurized cooling system it shouldn't be losing any fluid. My 18 that I bought had 62 miles on it when I drove it off the lot and it now has 38k on it and it hasn't smelled of coolant or dropped a mm in the tank. I saw someone said something about the weep hole commonly having coolant coming from it, that's a usual sign of a worn water pump seal or bearing. That's something they specifically look for. As most people stated obviously if your burning coolant that's an issue and most likely a head gasket, possibly but unlikely a cracked block. Now the people saying it uses fluid slowly, have you ever had a pressure check done? Because I have read some where that small small leaks are possible in our head gaskets near the corner peaks of where the barrels of our combustion chambers meet each other and the head gasket is really thin there. That's why I do compression tests every 10k miles and have monitored my compression since new, not a single change or fluctuation. The way I like it.
If head gasket leak into cylinder head, you will see blueish smoke coming from exhaust at startup. Also, make sure no foam is showing in the radiator when you take the cap off when warm but not hot. You don't want to drive it if you have a head gasket issue.It's normal for the level to go down over time with these cars. Shouldn't be any major drops. If you do notice your using more coolant than normal then there may be an issue.
