Plus Points:
The lowest running costs of any car on the road - cheap to buy, low servicing costs, cheap parts, cheap insurance, good fuel economy, and no depreciation.
A real crowd-pulling classic.
Even a mechanical incompetent like myself can service or trouble-shoot.
Parts are readily available.
They are surprisingly roomy in the front (I am 6-4) and boot (trunk).
Minus Points:
The power is hardly sufficient to pull the skin from a rice pudding.
The seats are pretty uncomfortable.
Brakes are only just adequate.
Rear seats suitable only for pixies, gnomes or children.
Okay, so as a car it has limitations - what "classic* car doesn't? Personally, I choose to ignore these limitations.
Their low top speed means they are best suited to city driving, but I have regularly driven on the motorway and autobahn and lived to tell the tale.
They are best suited to transporting 2 people, but I have driven with 4 adults in the car and all were able to walk afterwards (eventually).
They are not the most comfortable car for long journeys, but I have driven up to 800 miles in one stretch and have arrived unscathed.
I returned to Germany to buy another this year, which is as good an advertisement as you can get for any car. It is still relatively easy to get a good one there, but they are becoming rarer.
Get one while you can. You know it makes sense.
