Definitely go used Cam if you aren't going to keep the car. New car depreciation sucks.
I'm telling myself for my daily drivers I gotta keep it to as close to the end of lease period as possible. It worked out for the GTI, 3.5 years of ownership and delivered it to a Beyonder last night at 77600kms. I felt like I got my value out of that car.
Whatever car you buy, drive it! Hurts too much to sell a car you barely drove and taking a massive hit.
