I bought my car back in January. I paid $2600 for it. It was all original with only 33,000 miles on it!! After a tune up it was running great.
My first mod was a new muffler. I hacked off the nasty, old stock muffler and welded on a cherry bomb glasspack. Here's a video of the exhaust.

In June I pieced together a spectre modular intake. I also wired up sequential turn signals. This is definately the coolest thing I've done to my car. Here's the video of them.

Within the next few weeks I will be converting it from auto to manual. So hold tight for now. Also some suspension work to come.
