Let's suppose that while looking for a new car, I end up with a list of requirements that I would like my new car to satisfy. I proceed to put these requirements into one of the following categories:
Is there a more concise and/or idiomatic word or phrase for "not-so-nice-to-haves"?
drawback
: an objectionable feature : DISADVANTAGE The plan's only drawback is its cost.

Also demerit, disadvantage, inconvenience, shortcoming, stumbling block, detriment, nuisance
In particular this sense:
an object no longer of value to its owner but of value to others
If it's a feature designed into a car, it's of value to the manufacturer and other potential buyers, irrespective of how you value it.
It might help to consider the old marketing distinction between a feature and a benefit. The principle is that customers but something because it brings them benefits, but that designers of products tend to be more interested in features, irrespective of whether anyone else regards them as a benefit.
So I would interpret your "not so nice to haves" as features that you personally see no benefit in. A 'deal breaker', on the other hand, is just a plain old disadvantage.
I therefore propose the phrase "useless features".
The "Not-so-nice-to-haves" can be termed niggles - just minor annoyances and not big enough to be deal-breakers.
ODO:
niggle
NOUN
A trivial criticism, discomfort, or annoyance.‘However, apart from these niggles, the Monster is great fun to ride and is the perfect first big bike’.’
