2011 glk 350
 

My wife is looking at a 2011 GLK 350 with 29k miles. Its from a MB dealership; however, its not certified due to age. Local car and service history. All good. Asking 26k with navigation but no back up camera.
I am having it checked out tomorrow (mechanical and body). She has been driving a 03 Lexus that now has 200k miles. I estimate that she will driving about 10k miles a year going forward. I usually buy 3-4 years from current model year. Any advice about the GLK?
