300-400? I dont want ppl to respond with "Just get a Lexus"
" Dont spend ur $$ on cars"
I want to know detials like, E320 will break down or its a gas guzzler or Lexus has better performance....

I have an E320 with 4 matic wagon. Good points are that it's a big, comfortable car, with a lot of class. It's also the only car that's this big inside without being a monster on the outside, and it's very light (3700 lbs) for it's size. I've owned it since it was new in 1999. It's never had anything that I would consider a major problem, like an engine or transmission issue. Fuel consumption is good for a big car: 23 MPG (US) for average driving, up to 26 on the highway.

But it's had an endless list of small problems, most of which were surprisingly expensive to fix. Fortunately, I bought the extended warranty, but now that I'm done with that, the cost is mounting fast. For example, last month it burned a side view mirror. You can't make this stuff up...it literally burned, due to a shorted electric adjustment motor. Cost to replace was more than $400. The other side had gone a few months earlier, and was replaced while still under warranty. The starter simply died one day, and it took the dealer two days to repair. This was due to all the stuff that has to be removed in order to get access. If not for the warranty, it would have been a $1500 repair. I've had bad tie rods, a bad alternator, and I've replaced the seat controllers twice. The outside temperature display has been malfunctioning for months, but I choose to ignore it rather than pay the expected high price of fixing it. I've had leakage in the A/C system, which involved replacing a bunch of expensive stuff under warranty. The AM radio has never worked right, apparently that's a problem with all the E320's. Threre were a lot of similar problems. As you can see, nothing that you would call fatal, but expensive little issues that really blunt the joy of ownership. It's a difficult car to work on, so for much of this, you're stuck with dealer service. Repairs always seem to end up in the four figure range. If it was mine to do over, I would have bought a Lexus or Infinity.

Lexus = More quiet, refined, reliable, higher resale and has an easier nav

Mercedes = Better looking, more comfortable, and more sporty

I say get an Audi a6 but for more info on those cars you can look at automobilemag.com or car&driver.
