Welcome ikeane, good to see some new owners coming on-stream
As regards the rust spots, are you talking about the top of the inner wheel arch close to the power steerging fluid resevoir on the LHS of the engine bay? If so, this is a common problem caused by a lack of undersealing, if its serious, it may require a new inner wheel arch, its a time consuming job. If its minor then you might get a way with treating it and in turn slowing down the corrosion process.
Use your good judgement and you should be fine, remember, you could also use this as a bargaining tool!
