Everything I can find in books & on the web gives the name of the car as "Skeoch." However, both Skeoch & Skeogh seem to be actual family names, etc.
It's possible that all the sources I can see got the car's name from one incorrect source, but I don't have any particular indication of that. Can you point to anything that shows that it's Skeogh rather than Skeoch that's correct?
