Sorry to hear about your problems but that,s part of the fun (frustration) of owning a used car. I know what you feel, but..........
H & R sport spring, subwoofer and a 600 amps.....
Don't know if you made those mods yourself (or previous owner) but the cost of those ',frills'' would have been better invested in maintenance & repair, don't you think so.
