What was your first car ? Do u still have it and or drive it ?

A Suzuki Carry van. A welsh plug went when it was six years old - a tiny inexpensive part - but because it was hard to access it cost $600 to replace. The mechanic didn't bother to tell me that when one goes, all the others should be replaced at the same time or else they too will soon go.
I soon became so fed up with repeats of the same problem that I sold the van. Over 40 years ago now.
