Detailed and suitable for close ups as well as an asset for interior visualisation or a prop in larger scene. Most of the modificators are not applied so you can adjust them to your need (most importantly subsurfs) or keep them as they are. Comes in two colors (red, turquoise) and one bonus (Eric Clapton Crash #3).
Most shaders are based on Principled BSDF node introduced in Blender 2.79 so you will need 2.79 or later version of blender.
