The Mercedes A-Class . . .
is the cheapest car they make under their own name. It was intended to compete with the higher-end VW Golfs, and now of course with the 1-series BMW. The A-Class and 1-Series aren't sold in the US. The A-Class looks to be a permenant part of the Mercedes lineup, but it is not a big seller because it is expensive for a small car and Mercedes doesn't appear to be interested in expanding the range beyond one four-door body style and a choice of four cylinder gas or diesel engines. I don't think a six is offered, although I could be wrong. Compare this with VWs enormous lineup of Golf platform cars from VW, Seat, and Skoda. There four, five, and six cylinder engines, two and four door sedans, convertibles, wagons, etc., and below this level VW has smaller cars like the Polo. So does Ford, Renault, Fiat, Honda, Toyota, etc. Mercedes has never been a player in this market, which is where Chrysler could be strong, assuming that they could manage to build a decent small car.
It's nice some people have had good experiences with Chrysler, but company is so hit-or-miss that I just wouldn't chance it with my money. That's why the resale value on their products tends to be so low, as who knows if a shiny out of warranty Chrysler is a great car or an unmaintainable money pit? I have had two friends with Dodge trucks in the last decade. One regularly pulls a large horse trailer all over the southwest loaded with show horses. It also tows old race and collectible cars frequently, and gets used for commuting too. It is dead reliable, better than the Ford it replaced. The other truck never tows anything, just does regular duty, and the transmission didn't last 70,000 miles, plus many, many smaller issues. Both are extremely well maintained per Dodge's recommendations at the dealer.
For what it's worth, my family's experience with trying to get parts for the Eagle included two Jeep/Eagle dealerships in Dallas, two in Los Angeles, and one Dodge dealer in Los Angeles. Some of the parts guys were quite nice, but they would tell you pretty much upfront that you couldn't expect them to have parts available in a timely manner. At least once a back-ordered warranty part turned out to be the wrong part in the right box, causing the tech to have the car for a whole day only to have to reinstall the defective part since noboy knew when the right part would actually arrive!
