THE in the tagline: /ði:/ or /ðə/?

[CSHY]

Do you actually say THE in the following advertisement line as /ði:/ or /ðə/？

"Don't rent a car, rent THE car!"

Why has the dubbing speaker pronounced the THE as accented /ðə/？

He's contrasting 'the' with 'a'. Since 'a' is pronounced in the phrase 'rent-a-car' in its weak form, it only makes sense to pronounce 'the' in its weak form too.
