Advice on 2012 e350 purchase: carmax or CPO
1) Better to get carmax with maxcare warranty? Is this an easy choice or are there pitfalls I'm overlooking?
2) If I try to do my own adblue refill/replacement, does this void the maxcare or mb warranty?
Thanks. my dad used to own a 300sd which lasted a long time but I remembe the clackity clack and smell. guess those days are over and I'm looking to replace a worn out honda hybrid civic. Surprised to see such a big sedan has similar mileage. Thanks all




Doing your own maintenance will not void warranty. Just be sure to keep receipts, etc. so that you have proof of what you did.




ELW warranty can be refunded for any portion you don't use if the car is sold etc etc, so if you are debating a carmax vs mercedes ELW (and your car is eligible for an ELW) I would consider it before prices go up.
Good luck in your search




Glad you are happy with the price they gave you on your current car. The good thing is you can sell it to them even if you buy the car somewhere else. I did not get a diesel so I can't comment on that. If you are not interested in that, then you should keep looking. Carmax has a great internet search tool and will transport other cars in their inventory to your location, sometimes with no cost to you. In my case, they brought my car from another carmax 80 miles away for free, no obligation. It was reserved for me to look at before anyone else. If it had been farther away (i.e. more than 250 miles) there would have been a small transport charge.

CARMAX pricing is generally a bit more expensive than others and their trade in pricing has recently been far lower than dealerships (last year they offered me $17k for my car, the dealer offered $22.5k the following day) and don't forget that you can haggle at a dealership - using CARMAX as a comp if you want.
I believe that a CPO from a reputable dealer is more valuable than a CARMAX vehicle with an aftermarket warranty. The dealer may also offer more on your trade.

I sold them Lexus RX about 10 years ago because they offered several thousand more than the dealer. My mom replaced that with a new RX and when she wanted to trade that about 5 years ago they offered her $4k less than the dealer - go figure. Maybe they were valuing the old RX. Since then they've been very low on every car I've taken to them. In one case, my wife had a 2 year old Civic that we wanted to sell before she deployed for a year. They offered $6k less than an 3 year old Civic they were selling on the lot that had fewer options (EX, while ours was a EX-L with nav) and more miles. We kept it and traded it when she came back. The trade price was significantly more that the CARMAX offer a year earlier.
You may still get lucky with CARMAX but I think that all the good deals are long gone.




This was my first time buying from them and that experience was very straightforward and transparent. No pressure what so ever. All cars are open to browse. Of course most of the sales folks are no help other than getting you the keys to test drive. Again you can use their pricing as leverage to get a better deal from a dealer.

I will wait unti Jan or Feb if I have to.

But your assumption is correct, the OPs initial car is around 30 - 32 wholesale depending on condition, options etc etc
I chose the ELW vs Fidelity because it was a personal preference, it was for less years than Fidelity but I got a great deal deal from MB Austin.
I believe if the car is a CPO it is not eligible for a ELW but I could be wrong, if you use the search function I think a few posters have posted the cost of their CPO extended warranties, your best bet is to PM DrSAAB, he drives a lot of miles and CPO was worth it for him, and I think he also has a bluetech if I'm not mistaken, there is an old thread about extended warranties if you dig it up that may have the cost / pros cons
ELW is exclusionary, and compared to the CPO covers a few more things
In the car business, not everything makes sense, there are a lot of customers who will pay the extra money for a CPO car believing they are getting a better quality car, or will feel more comfortable buying from a Mercedes Benz Dealership.
At the end of the day a lot of consumers aren't so educated, and the cost comes down to a monthly payment, falling for the 4 square game at dealerships.

I know that most enthusiast cars are in better than "fair" condition but the reality is that this is what the dealer will offer. After refurb costs, the dealer will want to make about $2k above and beyond the CPO cost (about $1000-$1500 - the actual cost is a mystery), so figure the delta between what the dealer paid for the car and what they are willing to take for a CPO to be about $4k. They'll undoubtedly ask for more in order to ultimately get to that $4k.
When I last traded a car (Acura wagon) it had just come from the bodyshop from being rear-ended. The dealership knew the full history and saw the car before the accident, immediately after the accident and when the bodyshop got done with it. I was willing to take a hit on trade-in because I was getting diminished value from the other insurance company. Edmunds fair was $23k. The dealership offered $21.5k and ultimately gave me $22.5k. The car needed no reconditioning and it was on the dealer's website two days later at $28k. The independent appraiser valued the car pre-accident at $27.3k and post accident at $22.5k so the diminished value was $4800
CPO is even more strict in which they have to bring maintenance up and also get the tires to MB standard. Those are expensive items.
A car will need fair bit of recon from what you see at the auction.
Auction fee is $500+ on a 35k car, then transport (100-500) then pdr (200) then detail (150), usually bumper respray/ scratch removal (250) and then add tires and such (1000 for mb approved brands)
Then add the CPO cost dealer has to pay mbusa. (prob 1000-1500)
Even color makes a price diff on a luxury car. light blue is 1500 less than black for example.
so a CPO is probably about avg 2500 over cost of the auction car. then dealer profit of 1500-2500. SO 4k over auction is a decent deal on cpo.
If they get it cheaper on trade or etc then you can also save on the retail side.
