is it comfortable to sit in and are the controls easy to reach and use,
can I drive it for over 2 hours and still be comfortable when I get out,
can I see all four corners so that I can park it,
is the boot big enough for all predictable needs + 25%.
is the engine happy at 70 mph for long periods,
is the acceleration good (acceleration between 50 and 80 is more important than top speed or 0-60 time),
can it stop quickly and safely.
Whole life costs, including:
insurance group, tax band, annual servicing cost,
fuel consumption (miles per gallon or litres/100km), tyre life (expect at least 30000 miles) and replacement cost, service interval (expect at least 10000 miles),
size of car's road "footprint" compared with it's actual usable capacity (i.e. is it a bulky thing that will be tricky to manoeuvre and park but is quite small inside?).
Safety and security:
high NCAP rating,
Thatcham cat 3 security built in.
Not yellow, that's yucky,
Not white, it shows up the dirt,
Not silver, too common.
