I try to keep my vehicles as long as I can but I usually find a hot deal on something and think it's time to trade. Sometimes I just get the spring fever and pull the trigger on something different. Usually it's the truck I keep the longest however the Corvette is winning so far...I bought it with 1025 miles in 05 and I really want to keep it another year or two however I might get the "corvette fever" and decide to buy a newer, faster, and more fuel efficient Corvette but it will be a red one again.
