First things first, if you value having a turbo DO NOT reactivate the anti lag!
Well, need to narrow it down a little - they are fast, handle well, are thirsty, reasonably practical, crappy interior and require the front suspension replacing every 60k miles or so!
I had a hoot with mine whilst I had it, only did a couple of light mods (upped boost to 1 bar, intake, decat and full exhaust) and had a rolling road printout for 280HP, Used to get about 250-280 miles to a 60l tank. Only got rid cause I wanted something a bit more refined as 90% of my driving was going up and down A roads.
