RoloTomasi

I know it's kind of against the spirit of scooby driving (and believe me I normally want to feel all the horses under my right foot) but does anyone know if you can get after market cruise control fitted to a MY04 WRX?

I only want it if there's no negative effect to throttle response. I find myself doing far too many motorway miles lately, haven't got time for theB-roads on every trip ;-(
