It could be, but my pattern is to hold vehicles for a while and drive them into the ground. We will find out what the lifespan of this one is. Biggest issue will be in the battery life- and what portion of the charge it holds in five years vs cost of replacing with newer batteries.
Buy it. I just bought a SEL for $32K and 0% APR (plus did well on my trade). Between the tax and rebate I get another $10K back. Not too shabby and I own it now as opposed to later.
