maximum of 4,
don't for get most astons have 4 seats, as do some porsche's
if it has a middle seat in the backa nd can take 5, then its a family car.
and the 2 back seats have to preferably be designed for smurfs, so no normal person over the age of 5 could actually sit in them for any time longer than 15 minutes
If it has 4 seats and luggage space it's a Grand Tourer Rich ....................NOT a sports car
