If you loved your Park Avenue so much, then why did you get rid of it? You have posted many comments in the past on a lot of Buick threads that you don't like the Lucerne, but yet you own one now.
First of all, how do you know that I am the one who made those posts?? LOL. Well, you are right, and that is a good question. I guess it was just a dumb moment of impulsiveness. I bought the Lucerne because it was about the closest thing I could get to the Park Avenue in a new car and stay with a Buick. I usually buy a new car every 3-4 years, and I had the Park Avenue about 3 years. I really wanted the Enclave, but reasoned that it was too expensive and not practical for me. Well now of course I wish I had it to do over again. I wish I had stuck to my original plan and kept the Park Avenue another year, and then bought the Enclave after it was paid off. What I really wanted to do was keep my Park Avenue as a second car, but I just couldn't afford to not have the trade-in.
With the problems you are having and the "wet dog smell", it sounds to me like you bought a flood damaged car. Meaning that the car at one time in its life, has had significant water damage, meaning that it's been underwater. I can't stress enough to people, always ask for a Carfax or other similar report when buying either a used OR new car. I've seen even new cars (salesman demos) that have been significantly damaged and pieced back together to sell as new. Buyer beware! and that's for every make and model, from Hyundai to Bentley.
Demos are new cars. If a car has never been registered, it is considered a new car. Once a car is registered, it is then a used car. Though I am not sure if it applies in every state.
A demo often has several thousand miles on it before it is made for sale. Do you consider that new? The dealer certainly doesn't; once a car is driven off a lot, it loses nearly 1/3 of its value.
You should have gotten these very minor cosmetic details fixed before purchase. By signing and driving, you basically implied that you accepted these issues. Some people are never happy!
You bought a car with 60 thousand miles. You basically brought someone else's problem. You should have had the car checked out by a mechanic before purchasing.
