First micra buying advice please

Hello... hope you're all well.
I'm young to look at a Micra this weekend... cheap micra...
I understand the girl has to occasionally top up the radiator and there are a few other minor issues that she has mentioned.
So... I was wondering if you could maybe offer some advice as to what to look out for... check... places and things to be weary off when looking over the car....
Can I check anything to make sure this water issue isn't head gasket?
Leak down test etc...
Any advice will be very much appreciated
Thank you
Daniel
 
A leak down test to see if the cooling system holds pressure would be a good diagnostic, the water pump seals can leak so look for coolant coming from the small holes on the water pump. There's an O ring on the hard water pipe that goes into the back of the water pump housing that can leak. Otherwise Other's have had leaking heater matrices so look for damp carpets.
 
Could be leaking anywhere in truth, though if it is the radiator, water generally collects at the bottom as there is a lip of the front cross member and plastic fairing under that which would be wet. How many miles has it got on it?
