well i only have the two bikes to my name...but i'll include some of the rides my family owns/owned
Best
Yamaha YZF-1000R Thunderace - where as the Kawi is a big angry brute the ace is a softy,i'm more emotionally attached to this than it's much newer and superior rival..
MG TC - no reason,i just love this car
Mazda RX7 FD - the first thing i bought after leaving school,great car....i regret selling it everyday
MG A(2 sri 355) - i love this particular MGA because it has been with ma family for a long time,through good times and the bad,it's like a big sister to me...and it's a famous movie star as well...
Kawasaki Ninja ZX10R - 0 to 310kmph in 17 seconds,gives me the satisfaction of owning one of the fastest things on wheels in the country
Isuzu Trooper - cheapy jeepy...rugged as a rock and very cheap to maintain,love it..
Worst
Mitsubishi Pajero SWB - gave us a lot of troubles in the mid 90's,i have very bad memories of this jeep,although some were not it's fault...and because i was about 8 years old then i had to ride in the back seat,which is very uncomfy....
Fiat 1100 - no reason,i just hate this car
