Detects snack in vintage car feature (6,4)
I believe the answer is:
rumble seat
'vintage car feature' is the definition.
I can't judge whether this definition defines the answer.
'detects snack' is the wordplay.
'detects' becomes 'rumbles' (I can't explain this - if you can you should believe this answer much more).
'snack' becomes 'eat' (eat can mean a snack).
'rumbles'+'eat'='RUMBLE SEAT'
'in' is the link.
Can you help me to learn more?
(Another definition for rumble seat that I've seen is " extra perch".)
