I started with a couple of s2s and saved up for a 500 Griffith , it was only a few years old and bought from a main dealer in Harrogate , unlike any other car the hand over it Included a warning not to trust the fuel gauge , leave it more than a couple of weeks and the battery will go flat and it will leak in if you don't have a garage
Great old things though and I forgave it all it's problems , get a rover based one if your good with the spanners and sort it yourself .
I always thought the most exciting part of any journey in it was the nervous apprehension at the start wondering if you would actually reach your destination
Good luck if you buy one , I would personally choose a higher mileage regularly used example rather than a garage ornament .
