CX5?
Are you talking Mazda?
If so, I have not herd any bad reviews... I have owned a Mazda CX7 in my company..
Nice car but it was not my daily drive. I sold it to a mate and it now has 200,000 ks on it without a problem.
Haven't owned one but from everything I've read its the closest you can get to a classic British type 2 seater, think MGB Triumph TR series etc. But, without the oil leaks and temperamental SU's.
Stone reliable, a bit underpowered, but great for twisty roads.
