Agreed. Kick up some stink, and just hope you don't get a ricer. A good trick for getting a decent long term loaner in these instances - when they deliver the first one, go round it with a fine tooth comb, and pick out every minor problem. They generally will then upgrade to a larger class.
A few years back, I was in a similar situation, and they gave me a right crock of sh!t - some Mazda 6. It was winter, with snow and ice. Every time either the traction control or ABS kicked in, the headlamps dimmed to a candle. Lifted the bonnet, and found that the battery wasn't much bigger than a motorbike batt. Anyhow, got a BFO Pug 407 diesel - quite nice for French, and considerably better than any rice burner.
