This stylized Pontiac Grand Prix four-door sedan is supplied as one 1:87 (HO) master STL and is tuned as a paint-ready car prop for HO model railroads, suburban dioramas and display projects. The model preserves a clear three-box silhouette, slightly flared wheel arches, simplified headlight and taillight housings, and a low-relief grille and beltline that accept washes and drybrushing. Small badges and ultra-thin details have been generalized or removed to improve printability; badge regions remain as low-relief areas for decals or hand-painting. The body is a single shell (no separate windows or interior), reducing small-part handling at HO. Printing guidance: orient on wheels for best surface faces or upside-down with light supports under wheel wells if printing the single shell; resin users should place supports off main panels, FDM users should consider rafts or chassis splitting depending on nozzle size. Important: Miniature Reality supplies one 1:87 master STL only—uniformly scale the HO master in your slicer for other scales. Source note: asset comes from a legacy MeshRef stub and does not specify a prototype year; if you need year-accurate detailing, plan to add fine elements in CAD.

Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)
