Looking to Buy First Mercedes




I am looking to buy an ML 350 ( preferably diesel) and i wanted to know a few things.
How reliable are these cars? Any issues i can expect i.e transmission, HVAC ect? Are they reliable over 100k?
What gas mileage are you seeing (gas and Diesel). I am a territory rep so good MPG is important.
My comparison to this car is the Lexus RX 450.
Thank you!
If driving
40-50mph - 34-36MPG
60-70mph - 27-29MPG
70 - 80 and over 21-23MPG
Before I got ML was considering to get RX350 Sport. ML is much nicer ride but I think Lexus is more reliable.
CPO (Certified pre-owned) free through Mercedes benz dealerships only, extends power train warranty on used vehicles bought only at MB dealerships. FREE!
ELW - Extended limited warranty, adds bumper to bumper warranty to any used car purchased at MB dealership, car has to be under factory warranty to qualify. NOT FREE ($1600)
From reading cars with AirMatic suspension have high chance of requiring service after factory warranty expires
On Diesel models it's critical the service schedule (oil changes) has been done on time.
Get the light package (HID), Everyone complaints about how bad their lighting is without it!!
So consider a car that absolutely has HID Bi-Xenon light package.
Running boards on these cars generally are a negative as their just make your pants dirty and not enough step to them to actually be stepped on. so one without it may be beneficial if you dress up.

Buy a diesel because need it or you are intoxicated with the torque and fuel economy. Don't buy it because you think it will save you money.




Thank you!

BTW, according to my log, Im doing about 20K miles a year, its about $1K less for diesel vs gas. If buy it at gas station, there are more places to buy diesel at least $1 less per gallon.
If nothing happens - fuel filter which is about $150 at home or $350 at a dealer.

Just for comparison I would spend another $40 for gas if I use my 2009 C300 on the same trip.
Done this a few times to compare fuel consumption of both cars and even though I like my C300 better for drivebility it cant beat the fuel consumption of the heavier truck which buffles me.
My 2013 GLK also consumes the same fuel as the ML maybe because of the bad wind drag of the car on highway speeds.
Again, if you are doing a lot of highway driving and will keep the car for a long time get the gas version. You can also look at the GLK250 but dont compare the creature comfort of the smaller truck to the MLs.

The GLE Diesel 6cyl comes close, but only put 1300km on it from new total, but guessing slighty less than my ML going forward.
The GLE 4 cylinder diesel should do even better!
