As GG says, standard sound system’s are not as bad as they once were. You could go the route of replacing the speakers yourself for better ones. Admitedly You’ll be missing a few speaker’s and possibly a sub, but your wallet won’t feel so light!
I recieved an email of the mb sales repthis morning saying he had to take day off, but he will call me in the morning to arrange if I wan’t to go tomorrow or another day!
