If it has been parked up for 11 years, why is any of that a surprise?
A bit of time and effort and you will have a reasonable, low mileage example of what continues to be a pretty decent car.
I wouldn't be to hung up on the steering wheel position... The adjustable one only has three positions: up, middle, down, and it's hinged at the front of the dash and it has no reach adjustment.
Personally, I would start by cleaning it inside and out, and then go through it to form a list of jobs and go from there.
Trying to start it will be a waste of time as it will probably need a fuel pump, hoses etc... It's not like trying to revive a carb fuelled relic... Before you know it, you'll be £300 into it and it will still look like shit.
Clean it, assess the corrosion and go from there

If you don't have the inclination to do that, then the Omega probably isn't for you. In which case, you may as well list it on ebay/Facebook market place and let someone else deal with it. You'll probably get more than scrap for it too...
