It will grow on you to the good. I was renting all sorts of cars during 2013-2016 as Enterprise had a $30 weekend deal. So for $140.mo you basically had a new car for 16 days of the month with no insurance or maint to worry about. It was great. I got to see what almost every small-mid size car sold was like. My first Mirage experience was an Enterprise rental in 2014, beaten to near death, horrid clunks from the front, totally expired suspension (it had 35,000Kms.) and I thought it would kill me before the weekend was up.
It didn't and surprise!, my next Enterprise was a Mirage brand new, 100km on the clock. It was nite and day, the new one was amazing, quick, stable, and comfortable to me. And miles better than so many cars I had already rented. Focus, Festiva, Camry, Elantra, Accent, Versa, Micra, Fiat and so on.
It was the 1200 mike weekend that convinced me the Mirage was great. we got used to each other and I really was sad to turn it in. I requested a Mirage for every future rental but Enterprise must have released them all to auction.
