This is my 98 Grand Marquis Signature Series, which my grandfather gave to me. I havent done much with it yet. So far just a cold air intake. I plan on swapping the cylinder heads with mustang cobra heads and adding true dual exhaust. I'm still deciding between supercharger or twin turbo setup. I've seen it done on Marauders at car shows. She also needs a new paint job, interior work and new vinyl top.
