So can someone explain to me what the gains and losses are between the S280 and the Whoosh Hybrid? Trying to decide between these two right now. These are both within my budget, and I'm not considering any others, but I want to make an informed decision. I'm also limited to 93 octane. Looking for better performance on a daily driver, driven mostly between 1500 ft and 5500 ft above sea level. Comments and observations appreciated!
