Car dilema / what should i do?

[Mr. Krabs]

As you guys can see if you go back to my first thread, i am a bit indecisive when it comes to spending money. Here is my dilemma, i own a 2011 mercedes e-350 and i have been thinking of trading it in for the new range rover that's coming out. although, i have always loved the fastback mustang and there's a fixer upper i have an opportunity to buy and get it done to my style.

Should i just stay with the 350 and get the mustang? either way i will be spending around the same amount of money. should i just get the range rover? the 350 has been giving me constant problems and its been in the shop twice in the past year alone.
