The benefits of a cup are all immediately made nought the second you sit in one after having eaten.
IN my mind, unless you're going to make a track-only car, then get a "proper" 172/182 and get all the toys.
Late-model 172 with cruise control, climate, xenons, 1/2 leather etc. was what I wound up with. Mostly hassle free for 5 years......mostly.
