Prepaid main vs Stand alone A/B
 

My GLA45 is at 15K miles and had Service A maintenance done.

I was weighing my options between stand alone Service A/B vs. Pre-paid Maintenance plan at local dealerships, and saw that prices quoted didn't make much sense.

I've been quoted:

Service A: $325
Service B: $525

2 Pre-paid Maintenance Plan: $1365; 3 for $1915

At 30K, this model requires transmission oil/filter change on top of all Service A items done at 10K, and that's the only difference between 10K & 30K Service A's.

So how the are they charging $515 for this alone?
Also, Service B at 40K is identical to one at 20K, yet they're charging $550.

Do they think their customers can't do basic math?

I don't worry about A and B. I just take it to my local indy shop that specializes in M-B. I do the oil changes (at 5k) and air filters. At 30K I have the trans fluid/fliter changed and break fluid replaced.
