All done. It's a Skoda garage and not used to classics, but the tester was great and let me do the test with him (me in the car, him doing the checks, etc). He was gentle! Nothing wrong with her at all, which is just as well otherwise I'd have to shoot the mechanic, and that would hurt.
She's only done 1192 miles in the year. (France should boost this years mileage by some margin).
We put her on the emissions machine just out of interest, and even cold (having run for >5mins her CO2 was 7% steady, which was good, although she may be running a little lean which would account for low idle speed, etc).
Anyway, very happy indeed.
