Crossing 275k

Couldn't be a happier owner. Purchased a formerly leased car with 43,000 miles and have just crossed 275,000 miles with zero problems of any significance. Of course have had some things wear out that are normal, but the car remains powerful and absolutely dependable. Much better car than the 1990 Lexus 400 it replaced in 2003.

Makes other sedans seem unworthy.

I've owned my '99 E320 for 15 months now and could not be more satisfied; I purchased it used with only 78k miles and now have 86k on it. This sedan is a testament to the quality of German engineering and performance! People may claim the car is expensive to repair, but show me a car from this era or later that isn't (and I've had great luck with getting parts at reasonable prices from Rock Auto). The 3-valve V6 has excellent power - it will leap to 60 in 7 seconds flat while returning 25mpg (30+ on the highway). Laser-accurate cruise control, great seats, a 21-gallon fuel tank, and typical German highway prowess enable it to leap tall states in a single bound. The suspension has the magic ability to soak up road imperfections and then firm up in the curves - body roll is almost nonexistent. I was also lucky enough to get a fully-optioned model with heated leather seats, moonroof, Bose audio, Xenon headlights, rain-sensing wipers, etc. All this for a car that only cost $4200, I've put about $2500 additional into it to make it nearly perfect. Despite all these hosannas, there are a few problem areas with the '96-02 E320s you should know about when purchasing one. 1) Rust - the MB/Chrysler merger resulted in paint quality issues due to the move to water-based paint; check for rust around the wheel arches/door edges. ALSO - early E320s also have a serious issue with rust in the front suspension spring perches - check this especially if the car has lived in the snow belt. Mine was quite obviously garaged by the POs (an elderly couple) and has neither of these issues. 2) Rear window regulators - like VWs and BMWs, the rear window regulator guides are plastic and are prone to failure. I haven't had this issue either, but I rarely use the rear windows. 3) Valve cover gaskets - these will eventually leak, and may or may not be synonymous with clogged breather passages in the upper part of the left-side valve cover (it literally has a second cover on top of the valve cover). This usually results in leakage onto the exhaust system and a lovely burning-oil bouquet wafting through the ventilation system. I did enjoy this problem and had it repaired for around $500. 4) Transmission - the '96-99 models use the 722.5 transmission which is known to have issues at higher mileage; be sure to check the transmission shifts smoothly before purchasing the car and CHANGE THE FLUID & FILTER ASAP. FYI, when you first drive the car, it's designed to not shift out of 1st until about 2500rpm to ensure the cats are at operating temp. But excessively harsh shifting or the car hanging onto gears longer than normal is a warning sign. The '00-02 models use the 722.6 transmission which is essentially bulletproof. Also the tranny electrical connector (a $10 part) is known to leak through its O-rings causing erratic shift behavior (and if left unattended, can eventually cause the fluid to wick up the wiring harness and destroy the TCM), this is a simple and inexpensive fix but often masquerades as a much more serious issue - mechanics that are not familiar with the car can mistakenly advocate replacing the entire transmission. 5) Dash displays - on the '00-02 models, the separate left/right displays on the instrument cluster for the clock and PRNDL indicator WILL fail - check the dash photos for any 00-02 model for sale online and 90% of them will have this problem. The dash display on the '96-99 models are centrally integrated and immune to this issue. It's caused by the ribbon connectors inside the cluster separating, can actually be fixed for $0 by pulling the instrument cluster and wedging a small chunk of solid foam into the ribbon connectors to force it back together, but it's a fiddly business and many shops will advise to just replace it. 6) Oil leaks - the '96-97 E320 uses the M104 (straight-six) 4-valve motor which is highly prone to oil leaks; stay away from these for this reason alone. The '98-02 models with the M112 (V6 3-valve) motors are simply superior - more power, 100lb lighter, better mileage, lower emissions, and better flexibility. 7) Catalytic converters - these are known to fail around 80-100k or so, they disintegrate inside and cause horrible rattling noises at lower engine speeds. I destroyed one of mine blowing away some moron in a brand-new Infiniti who (incorrectly) thought he could jump me at a light from the left-turn lane. His expression when I shut the door on him was nearly worth the $1200 bill for 4 new high-flow Bosal cats (to be fair only 1 failed, but to be prudent I replaced all 4 and put in 4 new Bosch oxygen sensors, which is why it was so $$$ - I could have just replaced 1 cat for around $200-$300). With a timing chain instead of a fragile belt, the 3.2 V6 is known to go 250k+ miles without a rebuild. What you can't put a price on is how this silk-turbine powered LearJet glides over the road like a puck on an air-hockey table. You'll soon forget whatever you used to drive.

I have to say this car is best all around for commuting and long travel trips. Its not the best handling of the competition but it out accelerates all others in its class including BMW. I was in a 3 car crash at 70 mph once and walked away with no scratches. The bodyshop said if I was in a chevy, I would have lost my legs. Car is like a tank. The chassis is strong and stable. You feel very safe driving it at high speeds - but not as much as in the rain. Bose system is great- which is worth the option upgrade. The paint holds up for years and is strong against scratches and dings. I have had BMW, Lexus, Caddys, and Porsche - and I have to say the build quality of MB is the best.

Well, If You Must Know....

I bought the 99 MB E320, with 98,000 miles on it. I have owned this vehicle for over 6 years. Had to replace the AC / $1500.00, replaced the belt / $700.00..routine oil changes / every 4-5 months / $98.00 per service, need motor mounts, need electric work on brake lights, paint is severely peeled on top, front and back hood / paint job: $1500. But, as for the driving of the car? Well, I now have $219800 miles on it. It still drives smoothly, very powerful, very safe, handles extremely well. Yeah, it needs some cosmetic work, but, this is the most reliable, safest car that I have ever driven! I believe that with continued routine maintenance, I could drive it another 220,000 miles..easy

Rust

Have taken great care of this car. Only has 120,000 miles and the body is starting to rust really bad. This car has been washed and not in Michigan winters but for only about 5 years. I have been told that this happens allot because of the poor quality of the steel they used in 1999. Is anyone else having some of the same problems. What is Mercedes doing to help repair these cars rust problems.
