You clearly had a good base to work from. I have never heard of a mileage so low on a SC 430 lucky old you. Spent a little time looking at Japanese imports and there are some very low mileage examples there ,but still nothing of your ilk. I remember the shot of the undercarriage you posted and that was also clean as you might imagine given the miles travelled. You also laid down the process for restoring the seats which is what I would like to get on with next spring. Essentially I am just going to copy the process you outlined.
Initially I was just going to get the chequebook out and hit everything I wanted to do, but I have rethought that. Now I think it would be more satisfying to take more time and try to do as much as I can myself.
Have you ever seen another SC 430 and thought that's so good I wish I had that rather than the one you have? I have not , but of course I have not seen any others that were not just in photos.
