how much would the repairs cost vs. buying the allroad ridiculously cheap?

There's an Audi 2001 2.7T Allroad that the car dealership says that they'll sell it for
$3,000
cash. The catch is that they say there are repairs. Which include; exhaust manifold
replacement, power steering motor, and the driver's side door moto (window will go
down
but won't come back up). It also has about 125,000 miles on it? what would the cost be
to
repair all of this and would it be worth it to still buy this car?
