I think Eleanor from (the original) Gone in 60 Seconds is iconic because it was actually part of the plot. Of all the cars they had to steal, that one gave Pace and his crew the most trouble.

Pace tried to steal it at the airport but a woman was sleeping in it, he stole it but returned it at his gf’s insistence because it was uninsured, stole another and then it got smashed up during the lengthy car chase, and by pure chance Pace found a fresh one rolling out of a car wash which allowed him to finally finish the job once and for all.
