I just got back from a great weekend with my brother and cousin just west of Toronto. The C70 held up great, it's just that I really need to replace my bearings. The car was humming like mad the whole way, but we blasted some tunes and it was fine. We averaged about 140kph (87 mph) with the rest of traffic, and I was amazed at the fuel economy! Averaging 140kph, on 94 octane, with the occasional sprint up to 180, 1 to 200, and another to 220 just for kicks, we managed to get 7.9L/100km (30mpg) on the highway. I'm absolutely amazed and impressed with this fuel economy.
