The large aftermarket modification industry is both a blessing and a curse. We get to pimp our rides with all kinds of expensive goodies BUT when you want to upgrade to a newer model you'll probably only see less than half the cost of those mods on resale and even less on trade.
What tell heck @Flybuddy - you can't actually publish that kind of stuff here - if Karianne reads this and figures out the "investment" mods aren't monetary investments I'll be in the dog house
