Be careful of the brake issues.
The ABS light has pretty well been covered, and yes you can do without it if you are inclined to drive like that.
But the brake light on is a different problem.
Cheap fix would be new pads, if that is the reason for the light to be on.
But it could easily be a stuffed master cylinder, or caliper causing the light.
That should be investigated prior to you making a decision.

And yes - the price is too high, but that will depend on how keen she is to sell, and how keen you are to buy.

Good luck - if it is a good one, you will fall in love forever.
