If this is your first time purchasing a Mini then you should know all the models of Mini.

The Mini was reborn by BMW in 2002 creating the New first generation MINI. There were only the three models; Cooper, Cooper S, and Mini Cooper JCW. The Cooper has 115HP and got about 38 mpg. The Cooper S has 163HP with 33 miles per gallon. The JCW jumped to 200HP and still has 30MPG under its belt. The S and JCW first generation are Supercharged.
I am a proud owner of a 2003 Mini Cooper S. Mine has 58,000 miles on it and it still feels as new as the day I bought it. I get about 30-31 in town when I have the price of fuel in mind. Other wise full throttling it most of the time and slamming through the gears I get about 22 miles per gallon.
The second generation Cooper has 118HP with 40 MPG. S model has 172 HP and 36 miles per gallon. The JCW has a whooping 208 horse power and still manages to get 33 miles per gallon. The Clubman’s have the same engine as the regular coopers but slightly lower 0-60 times and miles per gallon being longer and heavier than the original.
Now on to the Countryman. The base model has 121 horse power and gets 35 on the freeway. The S model has 181 HP and with its All Wheel Drive system it gets 31 MPG.
