Trade a 04 for a 99. No way in hell mods don't add value onto a car unless the buyer is willing to pay more for then.

Plus I would never buy a modded car...could be a ticking time bomb and you never know what's been done to. You only have the sellers word. For all you know it could be a stock cam and stock trans

Can't afford to mod the 04....wait and mod it down the road.
