I am REALLY appreciating you and this forum. I say "you" because it is you who are taking your time to read this and offer your advice. I just put a deposit on a 2012 Sky Blue Metalic Prius V, III - and I hope I made the right choice. My commute is high-speed, 80miles r/t averaging 80-85 mph open freeway, minor grade. My question is this; does the MPG a Prius gets go down after 65MPH? If so - by how much? Do you have any observations for me? Thanks a bunch - P.S. You're probably thinking - where can I do 80 miles r/t at an average of 80MPH? Reverse commute - open freeway - no hills. P.S.S. If you're interested in reading on, you might want to know that I think I was three (3) Toyota dealerships worst nightmare of a customer; But I warned them all in the first 5 minutes of conversation that it was not going to be easy and it won't be fun for either of us. They said that was fine. So here's what happened; I used TrueCar info. I searched this forum thoroughly. I played one dealers' price off the other, I put deposits down with 2 dealers with contingencies, I got (at least) one sales person fired from one of the dealerships - (he actually didn't deserve to be fired IMHO) and the dealership I ended up going with ended letting keep my deposit sold the car to me at a $725 loss (under dealer cost.) I believe they did that not just to get "a sale", but rather as an investment in keeping their Toyota purchase quota up - which gives them better ranking and rates to buy other vehicles. Anyway, for everyone on this forum who felt they got a high price deal from a dealer, was lied to or just plain misinformed by a salesperson who just wanted the sale, I am one person who got a great deal. Am I happy about it? No way. Would I rather have bought the car from toyota.com? and I pick it up at my preferred dealer? Yes. Do I think the whole car dealership/selling process is antiquated? Yes. Do I think it will change? I hope so. Would I have paid $1,000 more for an experience with a sales person/sales manager/dealership VP that didn't make me feel like I was a piece of meat? Absolutely. For all of our sake. And for sales people at car dealerships - I have this bit of advice; people love to buy - but hate being sold. If you want to know more gory details...I'm happy to share. Final price? $26,510.
