Used 1999 Buick Park Avenue Fixer Upper for sale in Missoula, MT

I am trying to sell my 1999 Buick Park Avenue to whoever offers me the price of $500 (Not $100 or $1-$499). It is definitely a fixer upper, but I believe it will still run really good if the alternator is fixed. I just have a newer car, and don't feel like putting in the effort to work on a car I no longer drive. Plus, I am not a mechanic or car savvy. It needs a new alternator because it has to be jumped before driving. Also, only the driver side door opens at the moment. I believe the back doors are stuck on childproof lock, but unsure why the passenger side won't open. The driver's side door also needs a new master window switch to roll down the windows and unlock the doors since it is broken. I just use the key fob for unlocking/locking. So if you know how to fix the doors, this is definitely the car for you! It will need lots of work, and extra money put into fixing it. I'd like someone to buy it, fix it, and give it some tender loving care. The $500 is just to pay back my mother in law for the new battery, tire, etc. I saw this Buick, in great condition, is over $4000, so may be worth it for you to restore it to sell. Sold as is. It does need a good vacuum and wipedown but I cannot clean the inside due to doors not opening. I jump started it today and it seems to be running good.
