I am set on getting a Carrera 4 hardtop this spring.  Any feedback on the
best years for this car?  What options are most desired.  Any experience
with driving this car all year round through these nasty (-35 C) Canadian
winters?  Will it start in the extreme cold?

Is it okay to drive summer tires in winter when there is no ice or snow, or
is there something about the composition of summer tires that makes them
less effective in cold weather?  Mine are Vredestein 235-35-19 and
270-30-19, at 37 and 43 lbs.
