You might consider what many car enthusiasts eventually end up doing in this horrible climate; namely resign themselves to the fact that in south Ontario there are only 7 months of decent motoring (mid April to mid Nov). Hint: you will need a garage for winter storage.
Try this one on as an EXAMPLE:
female owner (Toronto) moving to the UK so she says
one previous owner
*engine size 2.5 L
*6 cylinders
*model 3-series
*odometer 160,758 km
*summer and winter tires both with rims
*plastic rear window replaced in 2007
*convertible top may be tempermental
*2008 SONY radio/CD player (product service plan until 2012)
Type of transmission not stated.

Has being driven in the winter by current owner which isn't ideal. However, if rust free then a good Krowning would do it.
Ask is $8000., but I'm thinking $6500 if it's mint and a manual tranny. Those motors pull hard. Tax would be $300 bucks or thereabouts.
Factor in $1000. for repairs/whatever and for $8000. you got yourself a nice spring/summer/fall ride. Then for another $8000 buy yourself an older Ford Explorer and during the non winter months park it in the backyard and the kids can use it as a fort.
