We took a CRD Caliber in p/ex a couple of years ago, first and last. VW engine and gearbox and it actually drove well. Plasticky as fuck inside and the windscreen was the most expensive one I've ever done. I think it was about £400 ordered directly from Dodge because no-one else could source one. That's considerably more than most with all the sensors built in, like Jags and Mercs!
I've heard that's the biggest issue with them, getting the parts at a good price.
Also, I've seen one of those Avengers up close and they are fucking massive compared to a Leon!
