1. Warmup takes a long time (compared to my E85 Z4). Approx 15-20min of driving to reach about 200 f.
2. When reaching 250 f sometimes i can drop a few ticks below 250 and reached 1 tick after 250. Is this normal?
3. Never went way beyond 250 f.

Don't think the water pump/ t-stat has been replaced or cooling system been serviced.

You should definitely do a coolant flush then. You will know when your water pump is about to fail because your radiator fan will start running like a plane getting ready to take off. Your temps are normal. Normal range is between 220 and 250F.
