buddy of mine has an Infiniti G35s, meets the criteria and is amazingly fun to driveI might be coming close to looking at a slightly used vehicle also. I plan to keep my current car but relegate it to garage queen/weekend/sunny day/track day car. It's starting to rack up too many miles doing everyday chores. Given that, I may try to find a new daily driver. Requirements are 4 doors, RWD, and manual transmission. Not many of those to choose from.
