What ever company goes out of there way to make good deals and to knock down prices and give you the best customer service they possibly can is a GREAT company to me and ill stay loyal to that company. Thats why i stick with boost-solutions and if i cant install it my self, ill either call up bernie "yugobernie" or ill just trailor my car down to GA so that Boost-solutions can work on it. Personally when it comes to My 300zx There are only 2 people i trust with it, George and Bernie there both VERY Z smart and know what there talking about and highly suggest them to everyone i know with a Nissan. If Z1 is a company you trust stick with them im sure there not bad same with SGP and alot of other stores but when it comes to me personally i like boost-solutions and bernie.
