Would I be allowed to take part? pi and GBA may have something to say about my 'qualifications'.
Why not? We can have a "currently does not own car / truck" category. You're likely not the only one...
...but GBA and pi would have you know that you HAVE owned one in the past
I would say:
Year
Manufacturer
Model
Body Style (defined categories: sedan, hatch, wagon, scCUV, cCUV, msCUV, fsCUV, SUV, pu truck, Marauder)
Number of doors
Number of Seats
Exterior Colour
Transmission Type (MT vs AT)
Transmission Speeds
Engine Cylinder Count
Engine Displacement
Engine Power
Engine Torque
Mods (yea/nay)
