A car such as an Audi Sline should come with all the extras on as standard, I've just got a 63 transit custom that has more on it than an Audi lol it's got heated front screen, front back sensors (display too), auto lights, auto wipers, hill hold, electric folding mirrors, aux point, USB port, kerb lights, cruise control, wireless hands free plays music wireless off iphone, soft leather steering wheel with all controls on, I mean come on Audi that's way more stuff. I have aux but no USB on mine but I do have a sd slot which I will prob never use.
