Rental Mustangs are V6 and completely meh compared to the V8 powered cars. I've owned two V8 Mustangs and test driven a couple of Cobras and late model GT's. I had a friend who owned a modded Corvette and he let me take it for a spin a few times, I've also test driven a few late model Vettes on top of that. My Father-In-Law owned a Porsche 911 and he let me drive it a few times. I owned a WRX-STi for a brief period and I have another friend who let me drive an E36 M3 and an E46 M3. Oh, I've also driven a BMW M Roadster. I've tested a couple 350Zs and a '06 Pontiac GTO as well. Plus, I spent 4 days with a 2005 Lotus Elise at my disposal and put about 300 miles on it during that time. So, I've DRIVEN these cars, not just ridden in them.
I've driven so many foreign and domestic family sedans (rentals, friends and family owned cars, etc) over the years that I couldn't even name them all...nor are any of them really worth mentioning in the company of the cars I mentioned above.
