I have a 2,2 E Coupe and i only can tell what the prices here in Germany (Europe) are. It depends on what condition the car is. Is it running ? does it have original body-style? original colour? rust? crashes? original interieur? a.s.o......
The S-motor is not lowering the price (i would say it lifts the price a little)
So my car is worth about 25.000 - 30.000 Canadian Dollars and the condition of it is a C+ (don`t know how you guys value your car in Canada, but we have school-notes from 1-6 for the condition)
Maybe it helps a little....
Greetings
