Its honestly a very tough call. Now with the Fuel issue getting resolved, if your pocket allows get a Turbo. The punch and thrill of that Turbo engine is great. If you are not a speed thrilled driver, get an oriel.
By the way on Motorway a Turbo overtook me when I was doing 130, so i decided to see if I can keep up. Therefore I floored my Oriel and surprisingly I could keep up prefectly at high speed. He was doing a constant 180 and that wasn't a problem for me to catch up and keep following. Then I slowed back down.
But the punch of flooring it as soon as the signal goes green is obviously superior to Oriel. In all honesty if you ask purely my opinion: the extra amount doesn't feel worth it to me as i don't plan on recording 0-100 times or laps on daily basis in city traffic.
