I did research for months and months and months. I explored all the pricing programs I qualified for. I did the math, I watched the videos, I looked over the pictures. When all the research was done I planned to buy a Q50 premium with no doubts in my mind. Then I actually saw and test drove the vehicles I had been researching. I test drove the BMW, the Mercedes, the Infiniti, and the Cadillac. When I first test drove these cars I tried the four cylinder models (not including the Q50). Based on the four cylinder engines it only re-affirmed I would get a Q50. Then I thought to give the ATS another chance since it would only be fair to compare a similar engine so I tried it with the V6. When I drove the ATS 3.6 vs the Infiniti Q50, I decided on the cadillac. It is all based on personal preference and I preferred the look and drive of the Cadillac. The Q50 is very sharp looking car with loads of technology, it just wasnt my preferred top choice. Im sure the Q50 is a great car as my family has owned two Q45's and one M37 and all were great, but for me, the ATS 3.6 with the black diamond coat was off the chain.
