My "outside the box" opinion. There really is a lot of time and work put into the car. From the pictures, the paint job quality looks outstanding.
Aside from that... I don't like the flames and the interior does not match the exterior and too much flashing and flashy stuff for me. If that was solid black and the body kit add-ons were toned down, it really would be a really good looking car. No where near 48k though. The person seems to be trying to profit money from the modifications and labor. nothing wrong with trying but mods are not a good investment.
