I too once had a BMW Isetta. Mine had four wheels but the back two were close together which made it very difficult to avoid the potholes in unsurfaced roads. I now own an 02 reg Honda CRV. Can you tell me if my engine has a belt or chain drive to the cam shaft? If it's a belt drive I need to get it changed as I have now done 80,000 miles. I do enjoy reading your replies to peoples questions.
