Dean chuckled, rolling his eyes with a bit of a smirk on his face "Only the best for you" He couldn't exactly argue how he treated his car. At more of the tour, he nodded. Heart being the engine. That made sense. Inner workings being the transmission. "All areas I'll be sayin' if you need to be checked up we go to a doctor" Or he would start reading all the books and sources he could to be able to help his car out. Oh, wait, whoops. He was planning to do that anyway.
