I'm certain this would be a common issue, but I can't find the answers I'm looking for.
Basically I imported my GT-T at the start of the year, the headlights looked almost perfect when it arrived. Gradually over the course of the year the headlights have gone cloudy and oxidised. I used plastic polish on them and it worked to a degree, but as soon as any car wash solution hits them again they turn to shite. The driver's side particularly up close looks like the plastic is stressed, something a polish isn't going to remove.
My question is - how much would be reasonable to pay for second hand set? And is it common for the headlights on an R34 to do this? Or are the lens replaceable rather than buying the whole headlight? The headlights are HID, they weren't converted to halogens at compliance
