You got the idea! I believe "Follow me home and we'll get it on with my AC Cobra" is very catchy but a bit direct. How about something more subtle like "Get in and get naked!"

Or maybe something along the lines of what you see at car shows... "A car is like another guys wife, you can look but you can't touch!"

"Cobra drivers like it sideways!"
"Cobra lovers like 'em topless!"...
