Keep in mind I'm comparing this to a 92 Civic VX. 2100 lbs, 92 hp, manual everything and all that jazz.
The Smart was poised on Pontiac's rutted streets, no bouncier than what I'm used to. Road noise was a lot reduced from my Civic, though engine noise was there, but not objectionable. All controls were logically placed and ergonomics were Honda-quality, which in my book is excellent. Seats were far superior to my Civic's.
The transmission shifts like a manual does, in that there is a pause in acceleration as it upshifts, which can be disconcerting if you don't know about it. Manual mode is far superior to auto. I found it got less noticeable as I drove and practiced. Turning radius is great (duh) and manual steering seems to be the way to go. It's more than fast enough to get ahead of traffic at a light, which is fast enough for me.
It looks like you could do all your own routine maintenance, oil changes look silly easy. Aside from that though, have fun. Everything is really wedged in there, reminds me of my old 87 CRX. Cargo capacity was enough for a commuter car, I could do my grocery shopping. Think EG civic hatch, ending at the rear seat.
The only thing that really irked me was the dealer's proclivity to add on extras to orphaned cars to jump the price. The one I looked at was a Passion coupe, priced at $15,6, which is $2k over the base Passion. The options looked to be a tach/clock combo, tinted windows, fabric protector, upgraded speakers, and pinstriping. How they get $2k out of that I don't know.
I enjoyed my test drive lots, and it will come down to whether they have a good (read <$15k) one available when I look to buy in a couple months. Gonna test drive a Fit and Yaris too.
And why such a small car? When has a GRM reader ever asked why?
