Have you tried bleeding the system ? Or maybe an electrical fault ?
C217 S63 AMG S Cabriolet ( Daily )
E87 116i with mild cams, headers, cold air intake making 136 bhp Lol (My Learning Track Car)
E36 328i Sport ( Project in making and future race/track car )

Check coolant level, perform a proper bleed procedure as advised by Wadi, check heater control valve/heat accumulator pump operation.

+1. At the very least, your cooling system has a big air bubble in it....or it might need the usual maintenance items of a water pump and thermostat. That's assuming it's never overheated, of course.
You need to know that an air pocket in the cooling system can prevent coolant from circulating, and can certainly cause the engine to overheat in very few minutes. Follow the bleeding procedure found in the FAQ thread at the top of this forum.

So I took it back to my work on the way there (5 min after I turned the car on ) it shot to the red so I turned car off and on and went back to cool and didn't do it again I took the sensors off topped up coolant but bleeder screw was right didn't want to brake it , the engine Temp. Never got off the blue and the air was only warm through the vents it's 150-200$ for a new thermostat

Stop driving that car! You may have already destroyed that engine! If no money for parts, no car until you do.
I feel sorry for the poor sucker you're trying to sell the car to. I sure would not buy it now. Hope the both of you enjoy the test drive.

Here's a quality OEM water pump for $48, and a quality OEM thermostat for $59. Then you need a gallon of blue coolant. Big Deal.
If you DON't do this, you'll destroy the engine. That'll cost THOUSANDS.
