The Cadillac XLR is no longer in production so only used models will be available. Since it was one of GMs most expensive vehicles even used it would probably be quite costly which not be smart for a first time car.

how do you change the heater core on a 99 cadillac deville? I need to know, "Kaiser."

could be a short in the electronic release on your trunk latch. if you have one of those handy lil remotes that opens your trunk for you, that meaans theres a little electronic switch that's hooked to your latch. if there is a short " 1 or 2 wires toucing each other or something metal in your car" that could be a problem. does it happen when you go over bumps ? or another reason is that your latch could be adjusted to loose and needs to be tightened, the loop lowered ect. could be many things with all of the electronics in cars today. it is either mechanical, " whole trunk lock assmbly is to loose" or electronic " the electric switch hooked to your latch, or maybe a short in the remote that keeps popping when not wanted. those are a couple options to think about.

There isn't one. The car is equipped with run flat tires from the factory just like it's corvette sister.

You can purchase an XLR microphone at Best in Music, Radio Shack, Fry's Electronics and many local electronics stores as well as music stores. Some super stores such as Wal-Mart might carry them as well.

under the hood

LOL

It's NOT worth using.

Underneath the van, between driver's and passengers seat.

Hard for a normal size guy to crawl under there when it has a flat tire and is even lower to the ground then normal.
