Hi

a mazda MX6 cheapest to buy, is there anything i've got to look out for if i go fro one of these

mazda rx7 (to expensive to insure but i do like them)

mazda rx8, i thought these would to expensive to buy but i've sen 2003-2004 reg cars for around £3000, most of the ads i'm look at the cars havn't done that many miles but most have had there rotary engine replaced, why is this and do they need to replaced every so often, is there anything else i've got to look out for. i like the look of this one http://www.autotrader.co.uk/classifi...1501?logcode=p
