Joss I would rather hear it from folk on here who seem pretty clued up on motors and engineering and don’t speak gobbled de gook and I can always ask a few questions and get a reply back which I can’t do online. I only use the mobility search as a rough guide as I’ve seen a good few motors being offered by local dealers but yet they ain’t on the M site. There’s a lot to learn like what does the TFSi stand for on audi as they like to show it off, is a 1.0ltr turbocharged unit as good as a say 1.5 unit, it maybe but only in cars of a certain size. Suppose its similar to you folk discussing towing capabilities, it’s interesting and maybe useful.
