My thought is for this kind of car, a big trunk and small backseat (2+2 grand touring coupe config) is just as it should be.
Slightly off-topic, but what's with the white Mustang, Steve...got one in your driveway now?
Yes (2016 Mustang GT Premium), although different that a RC350 it's a grand touring coupe configured in a similar way.
I'm sure he'll take the Lexus instead to any car meets...I've seen a lot of young people get hurt or killed in high-powered 'Stangs....more so than even other pony cars.
Most coupes rear seat room is a joke, even S-class size cars. Steve, I'm a huge huge Mustang fan, great pick up!
