'Jersey Shore' Vinny Guadagnino -- Calling All Haters ... Come Buy My 'Washed Up' Lambo (PHOTOS)

"Jersey Shore" alum Vinny Guadagnino doesn't care if people think he's a washed-up reality star desperate for cash ... he's unloading his white 2013 Lamborghini Gallardo on eBay.

Vinny posted a pic of the whip with the message, "Attention rich people! I'm selling my car ... I know I know what you haters want to comment, 'reality star, washed up, broke, need money, etc..' Feel free to!"

It's unclear if he's really strapped for cash or just cleverly wording his post to generate buzz ... like a good used car salesman would.

Starting bid is $169k and so far ... no takers, but there's still a week to go. If Vinny's pitch doesn't net a buyer, perhaps the mileage will -- he's only logged 1,190 miles!
