I’ll tell you what I know.
They’re crap, they were an apology for a car in their day, the original hairdressers vehicle, if you happened to be female and didn’t want to drive too fast. They lost the back end at just the hint of a greasy road, too much weight in the ends. No idea if and when they ever had a proper Porsche Engine, my memory of it was a VW Audi lump, bested speed and handling wise by a Golf Gti of the period.
Nicer looking was the 944, but it’s handling wasn’t much better and was a bitter disappointment to me when I bought one having traded a perfectly decent Toyota Supra, snobbishly a victim to badge marketing as I was.
If I were looking for some genuine mid life crisis classic Porsche thing, try and find a 356 or even build one of those kit versions there are about..
