I had one. Bought it new. I never managed to get the advertised 52 mpg though, only 48.
Was surprisingly well built, stiff, fast and nimble. Kind of a precursor to today's ricers like WRXs and EVOs. They've been used in many forms of racing...from SCCA to NHRA.
Here's a quote from an owner:
What things have gone wrong with the car?
The oil pump on this car went out at 250000 miles and took the engine with it. The motor was replaced with a Toyota factory unit (new long block).
At 505,000 miles the carburetor went at a local SCCA event (yes, the car is raced all the time, and has been for all its years). It now has a weber replacement which helped gas mileage and performance.
After 20 plus years and 500,000 miles, the interior was shot and had to be replaced.
General comments?
I truly believe that this is the gretest car ever made. It has never let me down, and I have never in my life had more fun in an automobile.
I will keep this vehicle forever. I love it like a member of the family.
