Oh dear.......................
This spend is fine with me, I get the sound I want, the 3-5HP claimed gains and a five year warranty, which will not concern me because in five years, someone else will own my car I guess!
If these people can knock out units that were previously priced at £215 for £108 and still make a profit, then it shows you, one, what they are really worth, and two, what a greedy group of people retailers are!
Just because we live in Britain people think we'll pay over the odds, well I say B O L L O C K S!!!
I'm Italian, I always haggle and always stick out for a bargain!
