Porsche 924 Lux
I bought the 924 when it was almost 3 years old for a massive £8k. Drove it `till Nov 87 then garaged it when my job changed and I no longer got a mileage allowance.
Got the car on the road again last year (2010) after the usual lay-up problems.. nothing major. So the car at 54.k miles and still all original is going better each time out.
Long may it continue.
