I have a 300 sallon on a 02 plate with 60thou on the clock had gs300 before, same engine but considerable diff in performance. I test drove a 200 sport just after buying is300. And at low speeds not much diff. But wen u want it to its got a lot more get up an go.ALOT:). As for mpg best on full tank 463 miles. Not great round town 20mpg tops. But Gota expect that. Ifu drive sensibly then is pretty good considering it's 3litre. Alot better than the gs I had before. Only one thing with the cost of fuel going on like it is. An u hot a lead foot will start getting pricey. In boots as well done 8000 since had it an all ready had new boots all round. And now need new ones. And it's not worth putting cheap tyres on a this sort of motor. Hope u get Wat your lookin for. Ps. It's nice to have a 300 wen pull up next to a 200. As though they look the same, but you defo will tell the diff wen pull away.;)
