Why I Will Never Modify the Suspention of a Vehicle

Everyone has seen a vehicle that has been modified in some way. Vehicles can be modified to many specifications ranging from tinted windows, a customized stereo system, and lowered suspension.
First of all putting a ton of money into a car is a waste of money considering it is unlikely that you will own the vehicle in 10 years. I have personally seen a stereo system installed into a vehicle, in which the system was worth more than the vehicle itself. I have installed aftermarket parts into previous vehicles, such as stereos, but I never placed so much money into one. I never got anything so fancy, just the basic AM/FM with a CD player.
Lowered vehicles are a nightmare. The are usually more expensive to tow, because they need special equipment.
Don't get me wrong I like the look of modified vehicles, but when it comes down to it they are more of a show car than a vehicle to drive for everyday usage.
