I don't understand why fixing the blower and oil leak is impossible. In my experience, any problem is fixable.
It is a big negative for me whenever I look at a car that has an inop odometer. How do you know when to change the oil? I'd repair or replace the odometer so at least it works. Its a nice looking car that someone would by at some price. I agree it would be a good idea to put the stock wheels back on it and sell the fancy ones separately.
And if I am trying to sell a high mileage car I put the miles in the ad so people know what you are selling. You'll get fewer calls but less rejection.
If you need an air filter bracket, I bet if you run a part wanted ad here you can get one.
