Vehicle I purchased with 50% off is a beast (7)

Ross

I believe the answer is:

caribou

I'm a little stuck... Click here to teach me more about this clue!

'beast' is the definition.

'vehicle i purchased with 50 off' is the wordplay.
I cannot quite understand how this works, but
'vehicle' could be 'car' (car is a kind of vehicle) and 'car' is found within the answer.
'i' is present in the answer.
This explanation may well be incorrect...

'is a' acts as a link.

Can you help me to learn more?

(Other definitions for caribou that I've seen before include "North American reindeer" , "North American Arctic deer" , "Wild animal" , "Large North American deer" , "Arctic beast" .)
