Just me but I would rather buy one built because you're always ( most of the time ) going to come out better. I've built them and bought them built, will take the already built almost all the time. Most dealers have no idea what mods cost and will under price them but not in this case. I saw a 2013 Tacoma double cab sell a few months ago in my town and they basically priced it around retail book. This thing had 40,000 miles, front and rear ARB air lockers, $2000 in suspension parts, TRD supercharger, ARE topper, new MTR tires, ARB bumper with a Warn winch, and a nice rear bumper, They were asking $25,000 for it and sold it for $23,000 which is about what the truck by itself retails for. If you start adding up the mods, new they were probably $15,000 plus, heck the supercharger was probably $7000 or more because it was dealer installed. I couldn't work it out at the time but was trying to figure out a way to buy it. Glad it didn't work out, just bought a fully built 1999 100 series with 98,000 miles and would much rather have the 100.
