Not a very good car..
924940
The weatherstripping on windows gets noisy from the wind.. The axles went out around 75,000 miles, front brakes go out every 30,000 miles... My average mpg is only 23 with a 4cylinder non-hybrid engine. Also, the seats in my base model LE are really uncomfortable, and the paint is very thin, chips easily from road rocks.  Interior has lots of vibration.. Lastly, the battery failed after only 2.5 years...

Had nothing but problems with this car. front suspension is a wacky design very hard to work on. tried to replace knock sensor even the garage couldn't get at it.replaced the starter was $300 that's very expensive. Also underpowered . probably one of the worst Vehicles I've ever purchased.

A lot of the interior is low quality plastics but the speed and handling are a dream. And that's what you really get a car like this for. It's a beautiful design as well.

The rubber on the tires fall off easily and the car doesn't always flip over.  The ones I purchased had some electrical issues and the headlights would flicker on and off until it finally died out a few days later.  I definitely would not buy this again or recommend it to anyone.  Waste of money!

Very bad car. Like super bad.
Engine yes it's great. But that's about it.
Nothing else worked. Oil was dripping on breaks. Springs popped through seats injuring my kids. Electronic mirrors worked for one week. Doors broke. Door locks broke. Door remote broke. A/C worked for maybe 2 years. Then not even vents. The car basically slowly but surely fell apart. I was very happy to get rid off it.

The car was very very slow! We're talking turtle speed. The design and the look of it. Its great! It looks really nice but very slow! Don't expect to win any race with this.

It's been a very good car, just be sure to take good care of it - change the oil as recommended, keep up on the fluids, stay on top of problems as they arise and it will be a great car like mine. I bought it used, the previous owners took good care of it. I bought it from them, gave it a new paint job, get it serviced every 3 months and it runs great.

This car looks good, but it breaks easily.  I bought two of them for my sons to find out if they'll be into RCs.  The wires in the transmitters aren't secured well.  I had to re-attach the battery power wire for both cars.  One of my sons decided to jump his car off a ramp and it broke after two jumps......so I'd advise no jumping.  This RC is ok but you gotta baby it if you want it to last.

Like other reviews said, this carburetor when at idle sets a "cruise control" because the throttle is open way too far. This caused issues with my clutch, as the rpms we're way too high at idle, I had to take the carb off and put the stock one back on. This carburetor, even after adjusting also did not run well at all at full throttle either, overall it is not made very well, and I would not recommend it, I was able to use the air filter though. If you really want a better carb, spend that extra money and get a quality racing one -around $60

Thought for sure it would be a grey or red hatchback, hopefully with the GTI trim.  But it's a yellow convertible dripping with flamboyancy.  Why no picture or description?  Kinda crummy too: not a great level of detail, not shiny, and the wheels don't even roll very well.

Doesn't reliably work. Sometimes, it works, sometimes it doesn't. There is a 30ish dollar version of this car that works more reliably.

scratches easily and 'chrome' coating on the plastic part is beginning to dull/fade already, car is kept inside garage and only driven once a week. Not good quality.

Not a fast car by any means. Reliable and great on gas yes, but that's about it.

we put it together easily, but one of the cars don't work as well as the other, car doesn't stay  falls off the track , it stops at all times very annoying,  I checked under the car no loose wires ,too bad I threw the box out, I would definitely return it, not fun when you need to keep  on reaching out to put the car back on the track every 2 to 3 minutes, very disappointed.

Its a beautiful car run smooth.  Its has a lot mechanical problem, sometimes door won't open, the engine shakes and steering shakes, when I try to turn it on the break pedal gets stiff, when I park the car moves,  it only has 45,000 miles I took it to the dealer 3 times they keep saying there is nothing wrong with the car. Now Im starting to record videos  so I could show the evidence to dealer.  The dealer did find other problems and they did fix it.

Lots defects.  Probably a lemon.  This is the last Mercedes Benz I purchased.  I will not be another mercedes benz owner after I sell the Sl500 and the E550.  I have owned 2 C350, 2 SL500, 1 GL450, 1 E350 and this piece of crap E550.  Bad transmission and suspension system on the SL500, GL450 and the E550.
