2006 Sciin xb - $1,200 (Norfolk)

I taught my sons to drive a stick in my xb.
I have some issues now, and they have their own cars.
I broke my wrist and no longer have the desire or strength to do the work myself.
Recently changed the waterpump, radiator, altenator, and battery.
It started with overheating and now has an electrical issue.
Headlights work but not blinkers, windows, and speedometer gauges.
Starts and runs, but it could be a head gasket.
I put in head gasket sealant, and she rums fine now.
Just don't know how long it will last.
I would like $1200 for it.
It's a 2006 and I think it has about 180,000 miles on it.
Thanks for reading
