One Vision, I paid just over £8000 for this. You can find early STi's for around 6 but anything less than that for a newage and I'd walk away (unless you can be sure it's not been abused).
Personally, I stick to V-Power but that's due to me believing that it has magical cleaning agents that other 'premium' fuels don't have. I have dismantled engines that have been ran on V-Power for thousands of miles and there was very little carbon build up compared to an engine ran on standard fuel, hence my preference.
My car has been mapped for V-Power but any 98 ron fuel would be fine.
Kaeo, UK car. The fog light covers were stolen some time ago so the previous owner fitted fog lights instead.
