Just a P5, MSP, RX8 and a 6S. Though, the next daily will be a CX7 I believe. Need more room for the kiddos. I liked the 6S. The MSP and 6 are two completely different cars that I don't feel comfortable comparing. The 6 just had Ford written all over it- You can tell there was a lot drawn from Ford on the car. The 6 was a great car to drive. Awesome for long drives. I drove it on a 2,400 mile trip last summer to the Keys and back averaging 90mph I still got 24mpg out of it and rode nice. It's heavy. It surprised me to find out it's curb weight is close to 3,800lb. if I remember right.
I would agree it's hard to compare them. Completely different cars for completely different buyers. The 6 is great for a DD, more space, decent on gas & power and handles good for all it's weight. We all know the MSP is just light, quick and fun to drive. For reliability I'd give a slight edge to the 6 but if you're looking at a first gen 6 it's still 6-10ish years old so it's kinda a wash.
If you can't have both, it really comes down to do you need more space in your car?
