"Cooler Than Me" singer [artist id="3559974"]Mike Posner[/artist] wasn't exactly all that cool when he was 17.

He recalls driving around in his first car on this week's episode of MTV's "When I Was 17," airing Saturday at 11 a.m. ET/PT on MTV. The singer gives a shout-out to his great aunt on the episode -- which also features Estelle and AnnaLynne McCord -- for being gracious enough to give him her old car when he was 17.

"My Great Aunt Dorothy -- hi, Aunt Dorothy! -- she gifted to me her '87 Volvo," he recalled. "And it was a really cool car -- in '87. The only problem was, I got it in, like, 2005."

The "Please Don't Go" singer would try to assert himself on the road but found it hard with his clown-car horn. "The great thing about this car was that it had this kind of clown horn. I would be really mad, like people would cut me off, and I'd hit my horn, and it would be like 'beep beep' and I was just like, 'Ugh.' "

We're sure Mike has updated his vehicle now to something a little cooler with a more aggressive horn to help ward off aggressive drivers.

"When I Was 17" -- this week featuring Estelle, Mike Posner and AnnaLynne McCord -- airs on Saturday at 11a.m ET/PT on MTV.
