About one year ago, I rented a SMART Diesel at the Montreal, Canada Airport Avis. I drove from Montreal to Trois-Rivieres, then back (about 175 km, 2 hours, each way) and filled the tank with $12.00 (US) of diesel fuel. OK, not fast on the math, but 350 km on 9 liters of fuel was truly impressive. Also, this was during a snow storm on major highways with monster passing 18 wheelers, even though I was at 100km/hr... I was impressed with the stability, feeling of security and legroom in my vehicle. I was hooked, and still am..... I Want One....... But, Why no diesel option??
