i have been looking at REDACTED values of used Teslas, my prediction is that Roadster used values will be pretty level but Model S values will fall in line with other luxury vehicles. However I do see a market developing in 3-4 years for limousines and luxury taxi services for model S. I think roadster will become collectible as people switch on to electric cars. However the longterm success with residual value will be down to Tesla and if they continue to support both cars longterm from a warranty and spares perspective. I love my roadster but I do worry that batteries by their nature are degrading with every charge and I wonder how long tesla will ensure replacements are available at realistic prices. A 400 mile battery is nice but it would be twice the price of a 200 mile one and many people may not be able to afford such a premium priced upgrade. It will be sell low if the battery fails or stump up for another. This fact worries me and should be considered by anyone looking at any electric car. What are your thoughts? I also wonder who would be willing to take an EV in part exchange for a different car?
