Cars - hate them!

I hate my Kia Carnival - just got it back from garage yesterday after they put in a new gearbox (under 3 month warranty) driving around today and whilst changing gear heard the most horrendous noise and car shuddered to a halt and refused to move - got out of the car to check the engine hadn't fallen out! Wouldn't have been so bad but I was due to pick the boys up across town in less than 30min. Phoned the garage who sold us the car and they came out with a lender and rang RACQ to get the Kia towed - managed to get the children with minutes to spare!
