Yeah but you fill up 2x as often!
Also, just wait for a big service. My mates 8 cost him a arm and a leg at his last service, but he did need quite a bit doing. Probably on par with the Zed.
On MPG, I'd have to say when gunning it they are about the same as the Zed, but on motorway driving, my mates 8 only ever sees about 22MPG whereas I get 29-30MPG for the same drive
Each to their own. Evos are very good for tuning. The engine is built very well which means decent power hikes dont cost the earth.
