Ya everyone and their mom tells me it is because of my age. It pisses me off cause I've been on my own insurance since I was 16 and it has literally been flawless, but zero reward at the end of the day.
You can whine about it all you want, but the fact remains that the 16-24 age group is a high financial risk for any insurance company. It sucks to be penalized for being in that demographic, but an insurance company at the end of the day doesn't really care. Add that to the fact that the GTI isn't exactly a family car, it's going to be more expensive to insure, than say a boring Taurus or Camry.
It just kind of boggles my mind when younger drivers buy sporty cars and then complain about the insurance. Either deal with it or drive something with a lower cost of ownership. Cost of ownership (and yes, this includes insurance) should
always be a factor when buying a car.
When I was your age, I was paying $250/month (close to $350 today, adjusting for inflation) to insure a barebones '97 Golf with a turd of an engine and power NOTHING. I just sucked it up and paid for it. It was what it was. You may try to shop around with other companies to see if you can get a cheaper rate with the same level of coverage you already have. But again because of your age group, there's probably not going to be a lot of difference. Doesn't hurt to look though...
My insurance went down significantly when I turned 25. I'm now paying $105/month for full coverage ($500 deductible) through Progressive on my 2007 GTI 2-door at 31 years old. That would seem expensive to some, but I also live in a big city that's known for car theft (Phoenix). Just as a comparison, I was paying about 50% more than that when I was still living in LA.
