do you have hid lights on your silver is200 jsg74,
as i see a silver one regular and its a pretty neat car :)
No real mods to mine other than the later style allows (11 spokes) but there are a few running round that do look nice
By the way I bought a previous car from powells and after 6 months noticed that the brakes were making a noise, I took the wheels off and found that the pads were down to the metal, so I wasn't overly impressed with their service department. That was a few years ago but it put me off them completely
