Spoken like someone who has never done a long road trip in a Miata. :) I have owned two Miatas, most recently a 2008 PRHT Grand Touring, which is about the most "luxury" Miata you can buy. I also have a 2015 Mercedes-Benz C400, which I've done 3 long road trips in since buying it in Oct. 2014. The Miata and the Benz actually get comparable gas mileage (Miata: 29mpg; Benz: 26mpg) on the highway, so the difference there is negligible. The huge difference is how you feel after having sat in each car for several hours. Miata seats are great for short road trips or the track, but absolutely horrifying after about 3-4 hours on the road. Plus, you can barely stuff any luggage in it! As someone who owned and used 2 Miatas as daily drivers (and each one being my only car!) from the year 2000 to 2014, you won't find a bigger Miata fan than me, but you have to be realistic--5 straight hours in that thing is enough to make anyone beg for mercy. The Benz is so much better equipped (OMG Bluetooth!), and so much more comfortable, that there is no comparison. Also, the C400 is pretty zippy. It's not a Miata, but it's a nice sporty feel.
