PROS: They are cute. - Classic styling. Fast enough to drive on modern expressways. Good handling characteristics. Low insurance rates. Reasonably comfortable interior and ride quality (for a sports car). Last of the great side curtain roadsters (before touring cars). Large enough production quantity, so anyone can have one. Good supply of service and restoration parts. Still generally affordable. Still rising in market value. Relatively easy to restore. Very easy to maintain and economical to operate. Generally reliable (once you figure out how to handle snap connectors). CONS: Some people have other tastes. It is not a minivan.
