Since I travel almost every week and have a rental car, that list would be way too long :)
But the ones causing a lasting memory were a Ford Expedition (terrible monster) and on the other end of the spectrum once a 350Z (that was pretty nice for a rental).
Actually it is kind of a fun game to arrive to the Hertz lot and find the stall number on the list, then walking up there to see what kind of car did they give you that week :)

Monte Carlo

Ford Focus
Ford Fusion

the two fords on my last I had both while my car was in the shop for 7 weeks for the engine replacement recall. I had the focus for 4 weeks and the Fusion for the last 3. that was a very bad time......

This thread isn't long enough.

Chrysler sebring
Nissan Altima
Chevrolet Impala

Ford Escape
Buick Lacrosse
Ford Focus
Chevy HHR

mazda 6 (its okai.. a decent handling boat)
toyota avalon (damn fast highway boat)

Protege (was almost new, never titled. Had been sitting at the dealership so long they apparently couldn't sell it as new anymore, so they turned into a loaner car)
Mazda 6 several times
Mazda 3 several times

Asked for a Mazda3 got a Nissan Armada :( After one day demanded something drivable was given a V6 Honda Accord which was closer. Having a rental car really makes you miss your 8!!!

Dodge Durango
Nissan Murano
Infiniti G35

Hyundai Accent! Went ten+ miles on Route 70 East from Keystone to Denver... in neutral.

and some other garbage.

Never had any problems with my 8.

Only having problems with my euro cars

Chevy Cobalt (wishin' now it was an Aveo, lol)
Mazda 3 (multiple)
Mazda 6
Ford Focus
Mazda Tribute (here's a tribute to all the crap SUV's on the road)
Volvo S60 (yeah, got a ticket going 120 in that thing...in a construction zone...at one a.m... it was SWEET...why not in my VR-8??? Hmmm...figures)

And for the record, within ten miles of driving each rental, at least five of my friends received texts that said "Ok, it only took three miles for me to realize my car is SO F%&*'n SUH-WEET!!!"

(And each friend replied with YEAH it is!!!)
