I would also like a Honda and would do a paint modification to distinguish my car. However, is one of the BTCC Scalextric cars better than the rest, or worse than the rest, based on dimensions? I have checked the dimensions of the stock cars, not accounting for replacement parts, on the internet, and found the following mm or grams:
Honda L=131; H=40; WB=82; FT=58; RT=58; Weight=74
BMW L=136; H=42; WB=83.5; FT=58; RT=59; Weight=70
VW L=150; H=42; WB=85; FT=58; RT=58; Weight=81
MG L=146; H=42; WB=85; FT=58; RT=59; Weight=72
