my c180 against others

am saving to buy another. the 1999/2000 model. the fuel efficiency, the low maintenance, the gripe, the balance, the shock absorbing capacity ie the gallop absorbing ability, the stallion look and the smooth driving performance. I wont forget how the a/c was until it got bad last year ever since then 've visited up to 8 workshop for the repair to no avail. you have read what I had as a car, then imagine what I would have had as a car if the a/c is working. readers, any help or suggestion on my a/c? one other thing, can we do without the HANESSY WIRE?
