Hi, I wish I still had a six speed box car. Fantastic for driving on the twisty roads of Scotland. No issues with driving to Spain several times with the six speed with lots of motorway cruising, no issues with the engine revving higher than with my current car with a five speed type 9. Current car feels a tad flat with the standard type 9 ratios in my current car. Type 9 with other ratios may be a different story. I'd recomend sticking with the six. Feels a much nicer gear change too.
