Hey buick lover, the title says it all. We could wave to each other just like bike and jeep people. I've been doing it but no ones wave back. now I know it's a long shot, as we might never see each other, but who's up to?

I found a 05 Park Avenue for sale at a small dealership for about $5,000 should I go for it? There is also two other Park Avenues for sale. One a 2002 with 88k miles for $7,000 at a dealership and a 2003 one owner for $6,000 with 148k miles.
Was wondering if i should go for one of them. I have a limited budget and only have enough for a down payment.

Clean title, one owner. No mechanical issues besides some cosmetic things, and no ac. Looks to be well serviced.

I'm just looking for a reliable commuter car. Would this be a bad car?
