Hi all, I've been on this site for about a year or so and have yet to post. Well, yesterday I bought my first car...well my first car with my own money . I am now a proud owner of a rust free (except for some trim on the door which is being fixed) 1999 Grand Prix Gt Coupe with 142,000 miles with lots of options! My old car was a 96 grand am and it is rusty. I am a happy camper! One question I did have was when it is in the sun (only seems to happen in the sun not during nighttime) the alarm randomly goes off. All windows are up and the sunroof is down and covered. Any suggestions?

Welcome. Could be a corroded ground, does it look like the carpet got wet?

Welcome

Welcome! Got pics?

welcome to the site is the alarm aftermarket?

I don't know about aftermarket. I will have to check! But the interior is dry unlike my last car that used to leak when it rained! Because it is in the shop getting a look over before she hits the road, I only have the CL photos. I love her though <3 She'* awesome. The GA will be my winter car so she stays nice!

Welcome, and a very nice GP. A white coupe just like mine.

Very nice. This car should last a looooong time if you drive it careful and keep it away from road salt.

That is a sharp GP! Have you tried to leave the windows cracked on a hot day just to see what happens?
