ok, where to start.
1, behave peoples
2, hyundais do not depreciate faster than any other make. It all depends upon age, milage, condition and model. ie. you buy a cavalier for 17,000 and after 3 yrs and 82,341 miles it is worth 4500-5000. now, take a 12,000 hyundai and after 3 yrs and 125,000 miles it is worth 3,000 dollars. where do you loose more? the rate is relatively the same, it is just that they were more economical to start with. Now, the tiburon depreciates a little less than the others, because of demand. It is more the class of car than the manufacturer. Heck, the Yugo was only like 6k brand new and one in good condition with respectable miles can still get 1200 to 1500 or more.
I just traded a 00 tiburon(17k brand new) and took it to the auction and it went for 7400. Retail it listed for 10,8k and they willget that in the city.
3, used to be that every litle factor went into insurance rates, including color and spoiler and rims. But now, all they llok at realy(beyond the driver) is: theft rate, replacement costs, saftey factors and structural durability, and location(as mentioned a fine line divides this, based upon higher theft rates and so on. HECK where i live it is a river, and insurance agents even ask me, which side i live on). As menitioned it is all tracked by vin, nothing else(as far as the car, anyway). You can change the engine add a spoiler put a 50,000 dollar stereo in and your insurance will not go up, UNLESS you request them to cover and itemize them.
