I'm strongly considering buying a Tesla Model S - this one or another one similar in age and mileage (hence cost) - Tesla Model S 85 TECH AND SUB ZERO PKG, PANO ROOF | Shift Motors Inc Price shown here is CAD which is about $52.2K USD with about 68K miles. I don't have any personal experience with fully electric cars other the little I've read about Tesla's. I drove a new 70D sometime last year and fell in love. But a new 70D with the same features as this one will be at least another $20K to $30K CAD north of this. 1. What are the things I need to watch out for? 2. What is the average reduction in range compared to new for an 85 with this much mileage? 3. With the proper spec winter tires, will it be challenging to drive this RWD car in the winter? I live in Southern Ontario. 4. Is it a much better idea to get a new one instead? My budget is about this ones cost. TIA!
