I would never ever put a panoramic in a non racecar. It looks silly and is unnecessary if people aren't dive bombing you etc.
That being said, I really liked the wink panoramic in my E36 M3 racecar. It provides more field of vision for sure (once you get used to seeing like 5 of each car if they're in the right spot...). Don't know why wink got bad reviews. Racer's Edge also makes a nice one IIRC.
