Although low engine hours would normally be considered a good thing, I'd be a little concerned about this. Why was a 2000 TBO engine overhauled or swapped at only 740 hours? Is there an underlying problem of which you should be aware? Study those logbooks carefully!
I know the cessna has more options for flying ie less restrictions
Actually, most of the restrictions would apply to the pilot, not the aircraft. For example, a Sport Pilot cannot fly at night or above 10,000 feet (unless within 2,000 feet of terrain). But since you're a Private Pilot, as long as you keep your medical active, those restrictions do not apply to you. If you have a properly night-equipped LSA, you can fly it at night with a PPL. If you have an LSA that can climb above 10,000, you can do so as a PPL. If your medical lapses, you can still fly an LSA, but only under Sport Pilot restrictions.
The 172 and most S-LSAs cruise at about the same speed. The 172 carries twice as many people, and burns twice as much fuel. You can easily get a repairman's certificate to work on and inspect the LSA -- for the 172, you'd need an A&P certificate to maintain (think two years fulltime schooling) and an IA rating to do annual inspections (another couple of years of study).
Rotax started out by building two-cycle engines for snowmobiles and jet-skis, many decades back. They graduated to four-stroke motorcycle engines (they make them for BMW under contract) about 30 years ago. The 912 series aircraft engines have been in production about 20 years, have a great maintenance and reliability history, and power something like 80% of the European light plane fleet. They have the best power to weight ratio in the industry. Rotax 912s are now a 2000 TBO engine, and make that easily (many go 1000 hours beyond it with no major maintenance requirements). They do require more routine service than Lycoming or Continental engines, but they cost a lot less (a new-in-the-crate 100 HP 912ULS is currently $19,000). Maintenance is a little different than it is for Lyco or Conti, so any mechanic who works on one (or any pilot who owns one) should really take the Rotax service and maintenance level courses (each runs one weekend, and costs about $500). There's also a heavy maintenance course for those who plan to split the case and do overhauls.
Whatever you choose, expect owning your own airplane to be twice as expensive as you anticipate (and three times as enjoyable). Good luck!
