Good to know about the rear seat limitations, my son's only 3, so not a huge consideration at the moment 😁. Although not many on the roads the ISF, will look increasingly dated up against the RCF and GSF over the next few years. At some point it would be good to take a step up to the more modern F models.
The Alfa stats are pretty impressive, knocking off close to 2 seconds from 0-100mph compared to the ISF / RCF.
