Hey guys, im back. I dont know if you remember me or not, but i need some help. I know bikes, not cars. So for the car info, i come to you. My girl has expressed some interest in lambo doors. Kits on ebay range from 200 bucks up past 1000. Im worried about water leaks, wind, etc. What kind of cash would i be looking at for such a kit, plus installation at a shop? If i cant afford this, i may pick up a catback instead.
