They depreciate extremely rapidly . I lost 45 % on my car in 1 . 5 years . That ' s three years worth of depreciation in half the time . Everybody I know who has sold their ST has taken a bath on the thing . This is a local seller who made a financial mistake and is trying to save their ass . They quote no sales tax but you will absolutely have to pay sales tax upon registering the car . Local prices are almost always higher because they ' ve already tried trading it in at places like Carmax or their nearest dealer and left a little shell shocked . They probably offered him $ 18 k . Some cursory math and basic tax calculations tells me he paid about $ 24 , 240 for that car if his current asking price is what he paid minus taxes . If that ' s true he ' s lost 29 % on the car already with 600 miles on it . If his price is folding his taxes in , he lost 17 %, which is still an accelerated pace to lose a lot of money very fast . Typical depreciation curves have you losing 10 % off the lot and another 10 % at the end of the first year for 20 %. Then you can tack on another 10 % at towards the end of year 3 for 30 % loss when your standard warranty runs out . Add 5 % more if you ' re feeling conservative . The car depreciates badly . Very badly .
