Nice car you have there...For price of the more popular, non-PI
cars, you can check out back of local magazine (eg. torque /
motoring) for an estimate of the price. As for the other factors,
you need to to talk to someone who own one of them to find
out.
Looks - I'll go for MR-S or RX8 (which you didnt mention)
Comfort - Most prob mazda 6, the rest are sport-oriented and when a
car is sport oriented, it is not really comfortable.
