I rented a 355 (and did you know it's pronoucned 3-5-5? [not 3-55] just FYI) when I was in Vegas a while back ago.  It is without a doubt among the best sounding cars on the planet and most memorable ways you can spend $750/day.  In just 24 hours I had 2 encounters with Nevada's finest...

A buddy of mine rented a Viper GTS (as a result, he now runs a 
Viper tuning shop  outside 
Austin, TX).  In this photo, the kind folks at Bellagio let us park and pose the cars in the valet 
drop off area.

Here's the harmonious rubberband that powers the 355. (And I 
swapped the plates on the car to give it a more personal touch.
And a bit of sound legal advice... Don't to that!)

This is quite possibly the 
nerdiest guy ever known to drive a Ferrari (me).

One of my encounters with Johnny Law.

Here's how the dream ended... I blew a hydraulic line (fluid got all over 
the engine and BILLOWED smoke -quite impressive).  And as a side 
note, it is one of the more interesting things I've seen trying to put a 
Ferrari on a flatbed tow truck.  It took a while due to that plate-like 
chassis and UBER-low clearance.  Then there's the 5am call to the towing
company... and convicing the operator that it's not a prank call, is a 
whole other story!
