In terms of looks, probably the Honda RA272. Trying to think of any other older open-wheel cars and I'm drawing a blank... There's the Mclaren MP4/4, but that's more of a classic 80's F1 look. Unfortunately the RA272 is in the Legendary dealer and probably won't be available for a month or so.
@Pizzicato1985 thanks a lot for the response, this Honda looks awesome.
Is there a way to get a notification when it becomes available again ? Do these cars renew at regular interval so I may have a sense of when it should be available again ?
