Decided not to go for the Nissan Maxima. Found a few issues with the vehicle albeit minor ones, nonetheless it is a 20K car as it is and already done 50K.
Been thinking hard and what I think is a better decision is to get a brand new Mazda 6 with a little bit more payment (25K approx). That way I will be at peace with myself and not worry about break downs soon, besides I get full warranty for 36000 miles bumper to bumper as well as 60,000 mile power-train warranty. The new car will have almost every gadget that the maxima has and more. I also get great mileage on the Mazda 6 (26/38 as opposed to 19/26). Getting a new car also means I get to choose the colour I want and also the colour of the interior. Finally I don't know where I will get to use the 291 ponies, the Mazda 6 is bundled with 185 ponies and that is more than sufficient for my needs.
Did I mention that I will get to smell the new car for at least 6 weeks from the purchase?
