Have ridden 30 some odd brands/models of tandems in 32+ years of tandeming . . . but never a Lamborghini!
Looks 'good' on paper, proof will be in riding. And Lamborghini has nothing to do with the car brand . . . just using the name and flashy graphics. At $500 and 'free' shipping it's a typical made in mainland China machine, all the way around. WallMart sells one even cheaper, as does Sears. You get what you pay for.
Let us know how well you 'love' it after your (St. Julian Winery?) tour in PawPaw.
A better (but pricier @ $3,000+)) choice would have been one of the 26" wheeled Co-Motion Periscope models that can handle roads/trails, with better frame/componentry + lifetime warranty to original buyer.
Would have been better to check out this forum BEFORE ordering, instead of after the fact.
Sorry, but that's our experience/opinion.
Pedal on TWOgether!

Attached Sears tandem . . . a couple hundred $$ less than a Lamborghini (Note: stoker bars 'expertly' assembled backwards).
