I agree with Sam.Modifying any car is a complete loss leader financially but if you love your car and nothing else floats your boat then go for it!
Don't listen to me as I've done all the maths,should have sold up years ago,spent a fortune and still love hearing my GTM supercharger whistling while ripping up through the old 6 speed manual gearbox!
Times are changing for the worst in the automotive world and I ain't letting my old girl go. Working on this winters mods as we speak.......
