OK, before I start I'm not thinking of selling, I love the A3 and have only had it for 6 months. Just wondering what people here think is the best time to sell to get the best return on the car's value. Mine was 6 months old when I got it so it had already taken a hefty hit on depreciation. I was thinking of keeping it till the end of the warranty then trading in for a newer one, maybe brand new, maybe 6 months or so again. I do a lot of miles so the car will probably be on about 55-60k miles by then. Would like to know your thoughts. I would change every year if I thought it was the most cost effective.
