An Arab sheikh’s first vehicle from Ingolstadt (5)
I believe the answer is:
saudi
'an arab' is the definition.
(Saudi is an example)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for saudi that I've seen before include "Eg, native of Riyadh" , "Not hard" , "one accustomed to hot, dry conditions?" , "Native of kingdom" , "Arab" .)
