I was at the MB dealer the other day picking up some filters. I spied a 2006 C280 4-matic in the showroom and went to have a peek.
$47,000 is the least expensive 4-matic equipped Mercedes? Suddenly, the IS250AWD looks priced VERY well. Personally, among the AWD crowd of the IS250, C280, 325ix Legacy GT and G35X, I would narrow my list to the Subaru for the wagon body and the Lexus for it's superb quality. I think the Mercedes is overpriced, the G35X has power but is off the mark compared to the IS250 when it comes to materials and dealer support. The BMW is a nice piece, but I still like the Lexus better, and the BMW is more moolah too. When the BMW went out of warranty, I'd have a nagging voice in the back of my head. When the Lexus went off warranty, I'd barely notice or care.
The Subaru offers great value with tons of go-power, AWD, and the much-desired-by-me wagon body, but the dealers are out of their league when it comes to selling against Lexus.
