I have a big car and a garage where it only just fits in terms of width. It is not just the doorway, but for the 1st 6 feet (2 metres) of the garage with a clearance of 2 inches each side (6 cm). I am ideally looking for some form of guide rail for the wheels to follow like you get in car washes, but can only find single spot laser pointers, which do not help. Any bright ideas or indeed a supplier of the wheel tracks
