I'm thinking of getting a used Model S to hold me over until I can get a pimped out M3 (registered at 10:45am on 3/31 in person). I don't really care what trim/options the model S has. Lower cost is better, I assume. But I also want the highest resale value in 2 years. I'm a very low mileage driver and take great care of my cars. I first thought about getting a new MS, but the depreciation in the first 2 years is dreadful. So I figured get one used, and suffer a lot less depreciation. Is a $10K depreciation for 2 years of a used MS in the realm of reason? I know about the ev-cpo web site, but are there any tips on getting a 'good' Model S that will maintain as much resale value as possible? I'm thinking a more popular model would sell better than bare bones with lots of miles. Should I get a more expensive (80s) MS, so when it comes time to sell it doesn't overlap with the M3 pricing? Basically looking for the cheapest way to jump the M3 queue. Private sale or CPO?
