I'm considering buying a used M4 convertible, C63 AMG S, or a 911 991. I am only buying one of these cars with under 30,000 miles and a perfect CARFAX. I want a car that will be a great daily driver I don't need lots of space the 911 has enough space for my needs. I want the car to have great realiablity and I also want the car that will look new and not dated for the longest. I have saved up for a very long time and have all my finances in order to deal with any repairs, but I would like any advice on if one of these cars will have more problems then the others. I am going to be buying one of these cars in the next couple months and I need oppinions from as many forums, friends, and professionals as possible. At the end of the day I am looking for the car that is the most fun with a good mix of not being dated quickly or being unreliable. I will be keeping this car for 5 to 7 years and my max budget is about $65,000 but I would feel better spending around $45,000 to $50,000 which would pretty much leave me with just the M4 as an option. Would the c63 amg s or the 911 991 really be worth the extra cash?

I am leaning towards the M4 the most and would really like to know if there are certain years I should avoid and if the competition package is worth buying. I can get a used 2015 m4 with around 30,000 miles on it from carfax for around $41,000 or a 2018 competition for about $55,000. Is the newer year with a competition package really worth the extra $14,000 or would I be just as happy with a 2015 model? I am coming from a 2007 328i coupe bmw so any of these examples will be a huge improvement. Thank you very much for your guys time I look forward to reading your responces.
