Hi Peter,
I can live with hand made and working on things that come loose, drop off, don't fit correctly, but ECU?? can't do a damn thing about that, hand made or not if the ECU is wrong, it's wrong and needs sorting quickly, mine was still not sorted for the year I owned it.
I don't want to compare a SLK with a Morgan, totally different cars, but for my purposes at the moment the SLK fits the job.
Cheers,
Ian
