No, it's a very good price for our market. Resale value is good here, not like in the states. Most others listed in this range are $23-25, and higher mileage, or base.
If it checks out and has no incidents on record (collision, flood, etc) then I would go for it.
2014s are the happy medium between most bugs worked out and old enough to be affordable.
I think the price is just lower because it's North Bay and not as large a market - slower sales and they want it gone.
( to the OP: ) I checked the car on-line and have to concur - from this distance it seems like a good buy. It has rear parking assist and a camera, which I consider essential. Make the trip to North Bay if you are interested, but call ahead to make sure it is fully charged. Be aware that this is the time of year when battery range takes a dive. You should get an easy 60+ in moderate temperatures, but maybe as low as 40 in the cold. Actual battery degradation is not a real worry with the Volt.
Things to take note of: only the rear rotors have been replaced. That would seem to indicate that they did seize up at some point. Ideally they would have been replaced with the nitrided OEM spec rotors but if that is important to you, (it wouldn't be a deal breaker for me.) ask.
The only problem I have had that was due to salt was with the wheel nuts. They corroded under the caps, distorted, and cost me $11 x 16 to replace.
Make sure it comes with the EVSE / charge cord. It's normally stowed beneath the trunk floor and might be missed at first glance.
Read the disclaimer carefully, especially regarding the Sirius radio. Again, not a deal breaker with me. I used mine for a total of about 5 minutes. The original warranty only goes to February, but you might be able to extend it at a price. Voltec warranty lasts for years.
Feel free to PM me if you like. When I'm in Toronto proper I'm usually on a mission, but more flexible out here in the West.
