I'm not a little guy by any means 6 ft, 210, and I'm comfortable, but any bigger than me may be pushing it. It does have a telescoping steering wheel so that helps out a bit.
I've been reading up on mods and they don't respond that well to bolt ons....and CAI mods may even hamper performance.....So I went out and bought myself a Wix air filter (it is what a lot of dirt late model guys run no HP loss over K&N and actually keeps the engine clean). I may eventually put on a Z-tube....intake tube off the 350z which doesn't have the air silencer part on it, and that just makes it sound meaner apparently, and possibly a plenum spacer which gives like a 10-12hp gain.
On a side note I'm really not used to a 5-speed auto. It is taking some getting used to...
