Yes, you can get good imaging in a vehicle, but that really requires kickpanels. This would run you about $350 at a shop. You may be able to find Q Forms for your vehicle (~120), but they really aren't that well made and can have some bad resonances around 75hz.

You'll get a lot more for your money online than you will in a BB or CC.
